Justin Timberlake and Jessica Biel welcome baby boy Silas Randall

It may be a while before Justin Timberlake and wife Jessica Biel can "Take Back The Night" - the two are officially parents after welcoming their first child, baby boy Silas Randall. Mom and dad are over the moon and doing well, and the "Sexyback" singer is 'ecstatic,' a rep confirmed to People.

Justin, 34, couldn't contain his excitement at becoming a first-time dad, publicly gushing over his leading lady and 'favourite collaborator' at the iHeartRadio Music Awards in March, during which he picked up the Innovator Award.

" Honey, I can't wait to see our greatest creation yet. Don't worry, Daddy's heading home right now to innovate by learning how to change a poopy diaper and get my swaddle on," he said on picking up the prestigious statue.

The private duo announced Jessica's pregnancy in January, after keeping the exciting news (and Jessica's bump!) under wraps for months. Justin finally confirmed with a touching photo on his birthday, in which he's kissing his 33-year-old wife's bump. "This year I'm getting the GREATEST GIFT EVER. CAN'T WAIT." he said in the caption.

This came soon after Jessica's friend Ariel Foxman posted a throwback photo congratulating her pal on her "impending motherhood."

Jessica has been keeping active throughout her pregnancy, practising yoga at home and enjoying hikes with her husband, as well as maintaining a healthy pregnancy diet. She is reportedly planning to open a children's organic restaurant and bakery in West Hollywood this spring.
