It’s official: Justin Timberlake will be passing on his suit and tie.

The singer-songwriter and his wife, actress Jessica Biel, have welcomed their first child, son Silas Randall Timberlake, their reps confirm to PEOPLE exclusively.

Reps say mom and baby are doing well and dad is “ecstatic.” Further details are not being released at this time.

Silas was the middle name of Timberlake’s maternal grandfather Bill Bomar, who died in 2012, while Randall is the musician’s own middle name, as well as his father’s first.

After months of keeping Biel’s pregnancy under wraps, Timberlake finally confirmed (on his 34th birthday in January) that the couple were expecting a baby together.

“Thank you EVERYONE for the Bday wishes! This year, I’m getting the GREATEST GIFT EVER. CAN’T WAIT,” he captioned a photo of himself kissing Biel’s bare baby belly.

According to Timberlake’s hashtags, the couple were making guesses as to the sex, after opting to keep it a delivery surprise.

Weeks before she gave birth, Biel, 33, celebrated her own birthday — and Timberlake once again took to Instagram to shower his wife with love.

“Happy Bday to the sweetest, most GORGEOUS, goofiest, most BAD-ASS chick I know. You make me smile ’til it hurts. I love you like crazy,” he wrote.

And the shoutouts continued as Timberlake picked up the innovator award at the iHeartRadio Music Awards on March 29, calling Biel his “best friend and favorite collaborator.”
“I can’t wait to see our greatest creation yet,” he said. “Daddy’s heading home right now to innovate by learning how to change a poopy diaper and get my swaddle on!”

Life just got even sweeter.

Dylan Lauren and her husband, Paul Arrouet, welcomed fraternal twins, son Cooper Blue and daughter Kingsley Rainbow, on Monday, April 13, the proud new parents confirm to PEOPLE exclusively.

Lauren, the founder and CEO of Dylan’s Candy Bar, and her husband, the co-founder of Marblegate Asset Management, “are celebrating the birth of their twins, a baby boy and baby girl,” says the couple in an exclusive announcement to PEOPLE.

“Her parents, fashion icons Ralph and Ricky Lauren, are overjoyed to welcome their first grandchildren and witness their daughter usher in the next generation,” Lauren’s reps add.

“It’s a dream come true for me,” Lauren, 40, says in this week’s PEOPLE. “We’re doubly thrilled.”

She and her husband, 44, chose a surrogate, she says, “because it was the way we wanted to start a family. I think it’s a wonderful option.”

Lauren decorated the nursery early with pastels, bunnies and blue and pink gingham in case the twins came before their due date (and they did!).

Now the candy entrepreneur is excited to share her love of all things sweet with the twins — once they are old enough. “I’ve been calling them the Twinkies, the M&M’s and the Doublemint Twins,” she says with a laugh. “Good things come in twos!”

Their little lady is here!

The Exes star Donald Faison has welcomed his second child, a daughter, with wife CaCee Cobb on Thursday, April 23, a rep confirms to PEOPLE.

“Meet the newest love of our life, Wilder Frances Faison,” Cobb captioned a sweet snapshot of her newborn baby girl.

The couple let son Rocco, 20 months, do the honors of announcing the pregnancy in October, appearing in a big brother shirt in a photo posted to their Instagram accounts.

But once the actor, 40, and Cobb, 37, found out they would be welcoming a baby girl, things took a new turn.

“It’s much different this time around,” Faison, also father to Kobe, 14, twins Dade and Kaya, 15, and Sean, 17, told PEOPLE.

“Before I felt like pregnancy was a little bit easier, right now she’s having the hardest time carrying this baby.”

Fortunately for Cobb, she eventually found her sweet spot: In December, Faison admitted his wife was feeling much better.

“It was a little touch and go at first, but she’s so amazing right now and she’s doing really well,” he said.

Late Friday, Cobb’s best friend Jessica Simpson shared her own photo with Wilder, captioning it, “Madly in love with my Goddaughter Wilder Frances Faison!!! I am beyond proud.” Added godfather Zach Braff: “Thank you to Cacee for growing this for Donald and [me]. #GodfatherII”

The couple, who were engaged in early 2013, announced their pregnancy with a video clip posted on Twitter in early January, which opens with them hearing the baby’s heartbeat for the first time.

And baby makes three!

Grimm star Claire Coffee has welcomed her first child, a baby boy, with husband Chris Thile.

“GRIMM Season Finale! @christhile & I had a baby! I DON’T KNOW WHAT’S MORE INTENSE!!” she Instagrammed Friday evening. “JK, it’s definitely childbirth, but watch tonight anyway! #buryingthelead”

“I’m not a patient person and I didn’t realize you had to wait 10 minutes for the double lines to show up on those little pregnancy tests,” the actress told PEOPLE. “Later, I was taking out the garbage and I saw these little pink double lines in the trash.”

“We’ve been having trouble finding names that we both like that are acceptable with the last name of Thile because my husband doesn’t want it to be too cutesy,” the actress told PEOPLE.

“It meant that my husband would be the one tasked with doling out puberty advice. I was also immediately excited about the baby bow tie possibilities,” she told Mini Magazine.

Kyle Busch is revving up for daddy duty.

The NASCAR driver and his wife Samantha welcomed their first child, a son, on Monday, May 18, he announced on social media.

Born at 9:45 p.m., Brexton Locke Busch weighed 7 lbs., 10 oz., and measured 21 inches.

“Mom n baby doing great!” Busch, 30, Tweeted along with a black-and-white photo featuring the new family of three.

The couple, who were married in 2010, documented Brexton’s birth on social media, using Twitter and Instagram to make the special announcement.

“Greatest moment of our entire lives! Mommy and Daddy love you so much Brexton Locke Busch!” the new mama, 28, captioned a second black-and-white picture snapped shortly after the birth.

She also shared a precious photo of baby Brexton puckering up for the camera. “This kissy face just melts my heart!” she wrote on Instagram.

After Samantha was diagnosed with polycystic ovarian syndrome (PCOS) and Busch was told his “swimmers weren’t exactly up to par,” the couple turned to in vitro fertilization (IVF) to get pregnant. In October, the couple confirmed they were expecting a baby, but due to Busch’s busy racing schedule, the rising NASCAR star hadn’t anticipated being present for much of his wife’s pregnancy.

Then a violent crash during a Daytona race in February sidelined Busch for most of the season, leaving him with a broken leg and foot, USA Today reported. The horrific accident, however, became a blessing in disguise.

“It stinks to be sitting on the sideline, but to be honest with you, the silver lining is to be home, to be with Samantha and to prep for our son coming. I think that’s been the most fun,” Busch said at an April press conference, according to NASCAR.com.

The first-time father is already back on the racetrack, finishing sixth in last weekend’s NASCAR Sprint All-Star Race.

Talk about a happy ending: Casey Wilson is a mom!

The former Marry Me star and husband David Caspe have welcomed their first child, a baby boy, PEOPLE confirms.

The actress, 34, announced her pregnancy in December, telling PEOPLE that she was “really, really excited” to be expecting.

And in January, Wilson was thrilled to find out that she and the Marry Me and Happy Endings creator would be welcoming a son in the spring.

“I thought I wanted a girl, but I almost felt relieved when I found out I was having a boy,” she later told Fit Pregnancy. “Having lost my mom, and having had such a close mother-daughter relationship, I felt like somehow, I wasn’t ready for a girl.”

But Wilson, who had a rough first trimester, had a strong support system in Caspe — even if he did occasionally want to get in on the pregnancy perks.

“He won’t allow me my comforts,” she joked to PEOPLE in March. “I got this big pregnancy pillow and he’s taken both of them for his own back and neck and shoulders.”

She added, “He’s like, ‘This is the best invention. This pregnancy pillow is everything I’ve ever wanted.’ ”

E! was first to report the happy news.

Keira Knightley is a mom!

The Imitation Game actress and her husband, musician James Righton, welcomed their first child, multiple sources confirm to PEOPLE.

Although PEOPLE confirmed her pregnancy in December, the mom-to-be, 30, kept mum on the news, and let her baby belly speak for itself in the weeks leading up to award season.

But after stepping out several times in gowns that kept her bump under wraps, Knightley — who later joked her ‘waist had disappeared‘ — opened up about the perks of pregnancy while walking the Golden Globes red carpet in January.

“Luckily, I don’t have lipstick. I only have nuts in here. It’s the wonderful thing about being pregnant. You just need to make sure you have snacks. So this is a snack bag,” she told Entertainment Tonight of her clutch.

While Knightley and the Klaxons’ keyboardist, 31, opted to keep the sex a delivery surprise, the expectant actress admitted to Ellen DeGeneres that the thought of having a son was frightening.

“Somebody said to me the other day, the problem with boys is — sorry, this is horrible — but when you’re changing their nappies, you can get the wee in your face,” she said during a February appearance.

“Jayde made her grand entrance at 1:59 p.m. today. She weighed 7 lbs., 15 oz. at birth,” the reality star Tweeted on Friday, May 29, tagging boyfriend Taylor McKinney. “She is beautiful and as healthy as can be!”

As for son Bentley, how will he handle the role of big brother?

“He’s so excited for the baby,” Bookout, 23, told PEOPLE in March of her 6-year-old little boy. “And I’m excited for him to have a sibling. I think it will be good for him to finally have to share the spotlight.”

Bookout, now a Chattanooga State college student and full-time social media marketing specialist, says that although daughter Jayde arrived first, marriage isn’t out of the question.

“We definitely want to get married and we’ve talked about it a lot,” she said. “But we aren’t trying to cram it all in at one time. After the baby comes and we get settled in with parenting two children, then that will definitely be our next step.”

Elizabeth Smart recently became a mom.

She and husband Matthew Gilmour welcomed daughter Chloe in February, her father Ed Smart confirmed to the Salt Lake Tribune earlier this week.

And though she’s become a notable activist for causes including underage sex trafficking in the years since her 2002 kidnapping and subsequent rescue, Ed Smart said Elizabeth, now 27, won’t bring this part of her life into the limelight.

“It is totally private,” he explains. “This is something she is keeping to herself and not trying to have out there.”

Smart, who wed the Scottish-born Gilmour in 2012, told PEOPLE last year, “That is my greatest aspiration — to be a mother,” and that starting a family with Gilmour would happen when it happens.

“We’ll start having kids and see how I handle that and then go from there,” she said at the time. “I don’t have a predetermined number in my head.”
