The "Mirrors" singer and his wife, actress Jessica Biel, have welcomed a baby boy into the world, reps for the couple confirmed with People. This is their first child.

While details about when and where Jessica gave birth are being kept private for the time being, they have reportedly named their child Silas Randall Timberlake. Reps also told People that Jessica and the newborn are doing fine, and Justin is "ecstatic."

Rumors about Jessica's pregnancy have been circulating since last October. And although the couple has managed to keep the news a secret, Justin made the announcement on his 34th birthday in January when the "Take Back the Night" artist posted a photo of himself kissing the belly of his pregnant wife on Instagram.

"Thank you EVERYONE for the Bday wishes! This year, I'm getting the GREATEST GIFT EVER. CAN'T WAIT. #BoyOrGirl #YouNeverKnow #WeDontEvenKnow #WeAreTakingBets," he captioned the photo.

The couple reportedly didn't know the baby's gender prior to the birth. However, Justin has been looking like a proud papa-to-be. And when he accepted the innovator award at the 2015iHeartRadio Music Awards last weekend, he couldn't help but hint at the fact that the baby was coming.

“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!”

And while Jessica has been out of the spotlight a little bit since she knew she was expecting, Justin made sure to show how much he loves and supports Jessica by posting another sweet Instagram message on her 33rd birthday last month. "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! --Your Huz," he wrote in the caption of the photo.

Congratulations to Justin and Jessica!
