Justin Timberlake and Jessica Biel have reportedly welcomed their first child together.

Jessica Biel Gives Birth

Timberlake and Biel welcomed a son, whom they’ve named Silas Randall Timberlake, a rep for the couple told People magazine. The baby is named for Timberlake’s maternal grandfather Bill Silas Bomar. Randall is Timberlake’s middle name and his father’s first name.

According to the rep, Timberlake is “ecstatic,” while Biel and the baby are doing well. Further details about the baby boy have yet to be revealed.

After months of rumors, Timberlake confirmed Biel’s pregnancy on his 34th birthday in January. “Thank you EVERYONE for the Bday wishes! This year, I’m getting the GREATEST GIFT EVER. CAN’T WAIT,” he captioned a picture of himself kissing Biel’s bare baby belly.

Timberlake most recently made reference to his firstborn child while accepting the innovator award at the iHeartRadio Music Awards in late March, calling Biel his “best friend and collaborator.”

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