Justin Timberlake and Jessica Biel introduce son Silas


“The Timberlakes are ready!!! GO GRIZZ!” he captioned the photo of his adorable son cuddled by his wife.

The couple confirmed the pregnancy last February on social networks with a sweet picture showing Justin kissing his wife’s baby bump.

“Thank you EVERYONE for the Bday wishes! This year, I’m getting the GREATEST GIFT EVER. CAN’T WAIT. #BoyOrGirl #YouNeverKnow #WeDontEvenKnow #WeAreTakingBets,” the proud dad wrote then.

Pregnancy rumors surfaced last October when Ariel Foxman, the editor of InStyle magazine, sent congratulations to the couple.

“Congrats @jessicabiel on your impending motherhood…Looking forward to the red carpet maternity style pix to come #tbt,” he wrote.
