The 33-year-old actress has given birth to a baby boy, Silas Randall Timberlake, her rep told E! News on Saturday.
This is the first child for Biel and the 34-year-old singer and actor. News about their happy arrival was first reported by People. The date the actress gave birth was not revealed.
After months of pregnancy speculation, Timberlake officially confirmed they were expecting a baby back in late January with an adorable baby bump pic of Biel and the caption, "Thank you EVERYONE for the Bday wishes! This year, I'm getting the GREATEST GIFT EVER. CAN'T WAIT. #BoyOrGirl #YouNeverKnow #WeDontEvenKnow #WeAreTakingBets." The accompanying photo showed JT planting a sweet kiss on his wife's big belly.
