Justin Timberlake gave fans the first confirmation that wife Jessica Biel, 33, is pregnant, with this adorable Instagram of the former N'Syncer kissing his wife's baby bump.

Timberlake captioned the pic: "Thank you EVERYONE for the Bday wishes! This year, I'm getting the GREATEST GIFT EVER. CAN'T WAIT."

Justin recently celebrated his 34th birthday but it looks like his biggest gift is still a surprise. He hashtag'd the snap: "#BoyOrGirl #YouNeverKnow #WeDontEvenKnow #WeAreTakingBets."
