Reps for the two have confirmed his name is Silas Randall Timberlake, and both Jessica and the baby are doing well.
People reports Silas was the middle name of Justin’s grandfather Bill Bomar, and Randall is the name of Justin’s father as well as his own middle name.
The couple kept their baby news private for most of Jessica’s pregnancy, and they confirmed the news only two months ago with an Instagram post from Justin’s account.
