It certainly is a “Beautiful Day” — Michael Bublé is a dad!

The singer, 37, and his wife Luisana Lopilato, 26, welcomed son Noah at 2:26 a.m. Tuesday, Aug. 27 in Vancouver, Bublé announced via Instagram, sharing a photo of his family.

“Overjoyed and filled with gratitude at the arrival of our son,” the new dad writes.

After announcing he and the Argentine actress were expecting their first child, the dad-to-be couldn’t contain his excitement over pending parenthood.

“I had just found out [we were expecting]. It was the greatest day of my life, so I just said, ‘You know, I’m having a baby!’” Bublé shared when explaining why he first broke the baby news to Reese Witherspoon.

In March, the couple discovered they would welcome a son. “We have just come from the hospital and the sonogram was pretty clear — it’s a boy! We are thrilled,” Bublé said at the time.

Finding out the sex of their baby boy coincided with the selection of the new pope, who happened to be from Lopilato’s native country. “She said, ‘It’s a sign!’ But there is no way we are going to call him Frank, even if it did work well for Frank Sinatra,” the singer joked.

Although the couple debated about names, Bublé’s main priority is to always be present in his son’s life. “I just don’t want to look back and say, ‘God, I should have been there more,’ because I have a feeling that I’ll never look back and say, ‘Jeez, I should have worked more,’” he said.

She once said there would be plenty of time for “freaking out” later in her pregnancy — and Kate Levering was right.

The Drop Dead Diva star, 34, and her husband Reza Jahangiri welcomed a son — one month early! — on Thursday, July 18, her rep confirms exclusively to PEOPLE.

Born at 9:35 p.m. in Newport Beach, Calif., Holden Robert Jahangiri weighed 5 lbs., 4 oz and measured 18 inches.

Since announcing she was expecting her first child, Levering had been enjoying an easy pregnancy — up until her water unexpectedly broke at 3 a.m., forcing the parents-to-be to scramble.

“We were in no way prepared for an early delivery. I had only been home from shooting Drop Dead Diva for nine days,” Levering tells PEOPLE, adding the couple had yet to buy a car seat or pack hospital bags.

While the mom-to-be had originally hoped to labor at home with a midwife before heading to the hospital for an all-natural birth, baby boy’s early arrival sent Levering straight to the maternity ward.

“Funny how things never turn out the way you think they will. Our midwife said that since he was preterm, we needed to head to the hospital so we could be monitored,” she explains.

Fortunately, while it was Levering’s first delivery, with a room filled with family and friends — including her husband, mother, sister, best friends, mother-in-law and midwife — the actress felt right at home. “I think we shocked the hospital staff with my tribe of support!” she jokes.

“I watch the videos we took and laugh because it was oddly like being on a television set: a crew of people scurrying about, focusing lights and prepping props. Nurses instructing me and poking around at me, much like the wardrobe, makeup and sound departments.”

Levering continues, “I took the directing role and bossed my family and friends around, instructing them where to stand and what angle to take photos from. All pretty hilarious.”

Once Holden Robert — whose middle name is for his late maternal grandfather — arrived, he was immediately taken to the NICU for monitoring before the proud new parents could spend time with their son. “I found myself yelling to my husband, ‘Follow the baby!’” Levering recalls.

“Five days later we were released [and] are happily dealing with sleep deprivation, a very hearty set of lungs, poop, barf and pee ’round the clock [while being] blissed out on baby!”

Jamie-Lynn Sigler is officially a girl with a kid.

The former Guys with Kids star, 32, and her fiancé Cutter Dykstra welcomed a son named Beau on Wednesday, a source tells PEOPLE.

No further details have been released.

After announcing their engagement in January, the couple surprised fans with even more exciting news only two weeks later: they were expecting! While confirming they would welcome a son, Sigler admitted she was even shocked by the timing of it all.

“We definitely thought it was going to be a slow relationship process and possibly an engagement — I felt like it was coming — so the baby definitely threw us for a loop,” the actress said in April.

Despite denouncing heels for the remainder of her pregnancy, Sigler sported a pair for her June baby shower, where she told PEOPLE she and Dykstra were having trouble deciding on their son’s name.

“We have a couple of [baby] names we’re toying with. We’ll call him one name one week and one name another week. I think we have our favorite, but you never know. We could change our minds when we meet him,” she said at the time.

They’re officially three peas in a pod!

Actor Josh Duhamel, 40, and Black Eyed Peas frontwoman Fergie, 38, welcomed their first child on Thursday, Aug. 29, their rep confirms to PEOPLE.

Son Axl Jack Duhamel weighed in at 7 lbs., 10 oz., the rep tells PEOPLE.

After announcing the pregnancy on Twitter, the reality of a baby on the way set in when Duhamel witnessed his wife’s first ultrasound.

“It’s very exciting … [It's] unlike anything you’ve ever seen. You’re like, ‘Wow, it’s mine,’” the dad-to-be said in February.

For her part, Fergie — who celebrated with two baby showers — joked the pregnancy was a long time coming as Duhamel wanted to start a family after the first date. “He’s going to be an amazing father. He’s got natural parenting instincts,” she told PEOPLE in April.

The parents-to-be tried to keep baby’s sex a secret, but during an appearance on LIVE with Kelly and Michael, Duhamel hesitated before picking out a blue onesie. They did, however, manage to keep their son’s name under wraps.

“Some people may not like it, some people may think it’s really cool, but we don’t really care — that’s why we’re not telling anybody,” Duhamel explained.

Coinciding with baby boy’s birth was a special surprise from new dad Duhamel: a push present.

“You got Christmas, you got birthdays, you got Valentine’s, you got Mother’s Day, you got every other thing in between … I don’t know who came up with this push present idea, but I think it’s probably a female,” he joked to PEOPLE.

It’s a boy!

Extra host Mario Lopez, 39, and his wife Courtney welcomed their second child, son Dominic, on Monday evening, Sept. 9 in Los Angeles, he announced via Twitter.

“It’s a boy!!!!!!!!!!!!!! Please welcome Dominic Lopez to the world,” he wrote. “Couldn’t be happier … Courtney and baby are doing just fine.”

The family’s newest addition, who weighed in at 7 lbs., 2 oz upon his delivery via c-section., is named after Courtney’s grandfather and will go by the nickname Nico. He joins big sister Gia Francesca, who turns three on Wednesday.

Since the February reveal that there was another baby on the way, Mario and Courtney have concentrated their efforts on soaking up time with their firstborn — including throwing her a princess-themed birthday party — as they prepared her for the baby’s big arrival.

“She’s pointing at the baby and saying, ‘There’s a baby in there,’” the doting dad told PEOPLE, adding their decision to keep the sex a surprise didn’t sit well with the soon-to-be big sister.

“She wants to know if it’s a boy or a girl, but we don’t know because we’re waiting to find out. That’s kind of tough sometimes — we just don’t know!”

But as Gia’s excitement grew, Courtney joked she wasn’t sure how much her toddler actually understood. “Gia kind of understands that there is a baby in my belly,” the mom-to-be said shortly after announcing her pregnancy. “She also told me our dog Julio has a baby in his belly — so who knows!”

As for regaining her body after baby, Courtney admitted to PEOPLE she’s hopeful she will shed the pregnancy pounds as quickly as she did following the birth of her first child.

“My husband is the most supportive man on the earth. He loves my booty,” she said in June. “I lost the weight pretty quickly the first time, so I’m praying it happens the second time around.”

Surprise! It’s a boy for Jordana Brewster.

The Dallas star, 33, and husband Andrew Form “are excited to announce the birth of their son, Julian Brewster-Form,” her rep tells PEOPLE. “They welcomed their son via surrogate and the parents are overjoyed.”

The couple, who have been married for six years, had been considering children as of late. “We’re thinking about having kids but I don’t know when it’ll happen. I feel very ready now,” the actress told Latina in January.

If all goes well, Brewster and Form, a producer, hope to eventually add another little one to their brood.

“I definitely want to have kids. I want two. I grew up with a sister, but I know Andrew would love boys, but I’ll take what I can get,” she said earlier this year.

“One thing that I’ve always sort of loved and been enamored by is the idea of having twins. My dad was a twin, so it runs in the family. Fingers crossed.”

Kathryn Morris is a mom — times two!

The former Cold Case star and actor Johnny Messner welcomed twin sons on Wednesday, Aug. 21 at Cedars Sinai in Los Angeles, Calif., her rep confirms to PEOPLE.

“Jameson West Messner and Rocco McQueen Messner are now cozy at home loving family life,” the new parents tell PEOPLE exclusively. “We’ve been blessed with 14 lbs. of love from above with these angels. Healthy sweet boys!”

Both baby boys were born at 8:12 a.m., and weighed in at 6 lbs., 14 oz. and 6 lbs., 10 oz.

Although the initial discovery that Morris, 44, and Messner, 43, were welcoming twins took them by surprise, the new mom is thrilled her baby boys share a special bond.

Jameson and Rocco – Kathryn Morris

“When the doctor sensed twins from some specific HCG levels in my blood work, he brought us in for the ultrasound and said, ‘Let me just check on something I already know … Okay, there’s one for you and one for you!’ We were shocked and ecstatic,” she recalls. “Now these brothers have a built-in best friend for life! Who doesn’t want that?”

Now almost four weeks old, the 2Bdr/1Bath actress shares that Jameson West — whose name is “a combination of several family names” on Morris’ side — and Rocco McQueen — whose name “represents everything Johnny’s about” — are starting to let their polar-opposite personalities shine through.

“Jameson has a sweet and fiery Irish swagger and Rocco has a laid back Italian cool to him,” Morris says. “We had some names in our pocket, but once they arrived we instantly knew who was who.”

Rocco and Jameson – Kathryn Morris

As for the cheek-chomping photo at left, “Jameson was learning to breastfeed in the hospital but got a little confused where to latch on,” Morris jokes. “Rocco has some payback in order.”

The proud parents lovingly refer to Jameson as The Boss and Rocco as Mellow Yellow — together they’re called The Dirty Messners.

“The love we feel is overwhelming … a love we never knew existed. We are truly blessed,” Morris and Messner tell PEOPLE.

In April, three years into their relationship, the actress and Messner announced they were expecting twin boys. “She and Johnny couldn’t be happier,” her rep told PEOPLE at the time.
