Congratulations are in order for Justin Timberlake and Jessica Biel.

The pop superstar, 34, and his actress wife, 33, welcomed their first child – son Silas Randall Timberlake – PEOPLE reports.

According to their reps, both mom and baby are doing well and dad is “ecstatic.”

The couple has remained mum on all other birth news – including their son’s actual birth date and weight/length – at this time.

After months of keeping Biel’s pregnancy news under wraps, Timberlake confirmed their happy news — on his 34th birthday!

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

And last month, when Timberlake picked up the innovator award at the iHeartRadio Music Awards, he called Biel his “best friend and favorite collaborator.”

“I can’t wait to see our greatest creation yet,” he added. “Daddy’s heading home right now to innovate by learning how to change a poopy diaper and get my swaddle on!”
