Justin Timberlake and his wife, actress Jessica Biel, have welcomed their first child, Silas Randall Timberlake, representatives exclusively confirmed to PEOPLE. The couple are currently keeping additional details private.

Biel kept her pregnancy a secret until January, when Timberlake Instagrammed a photo of himself kissing Biel’s pregnant belly with the caption, “Thank you EVERYONE for the Bday wishes! This year, I’m getting the GREATEST GIFT EVER. CAN’T WAIT.”

Timberlake summed up his anticipation at the iHeartRadio Music Awards on March 29. “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!”
