Jessica gave birth to Silas, the couple’s first child, earlier this month. Silas was the middle name of Justin's maternal grandfather Bill Bomas, who passed away in 2012. Randall is Justin's father's name and also the singer's middle name.

The "ecstatic" new parents were bursting with excitement leading up to the arrival of their first child. While accepting an award at the iHeartRadio Music Awards earlier this month, Justin gave a sweet shout-out to Jessica.

"You can't have innovation without creation, so finally, I want to thank my best friend, my favorite collaborator — my wife Jessica, at home, who's watching," Justin said as he accepted the prestigious 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."

And former N'Sync bandmate Joey Fatone revealed the boy bander has been looking forward to fatherhood. “He’s always wanted a child,” told HELLO! at Saturday Night Live’s 40th anniversary.

Despite his excitement, Justin took months to confirm the pregnancy finally announcing on his 34th birthday that his wife of two years was expecting their first child in January. He shared a photo on Instagram showing him kissing Jessica's pregnant tummy, along with the caption: "Thank you EVERYONE for the Bday wishes!

"This year, I'm getting the GREATEST GIFT EVER. CAN'T WAIT. #BoyOrGirl #YouNeverKnow #We DontEvenKnow #WeAreTakingBets."
