Justin Timberlake [1] is one happy birthday boy! On Saturday, the singer shared what is arguably his cutest Instagram picture ever. The sweet snap shows Justin kneeling down in front of Jessica Biel [2], holding her waist, and kissing her growing 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," he wrote in the caption. The post marks the first time Justin and Jessica have opened up about the pregnancy, although *NSYNC's Joey Fatone reportedly confirmed the news [3] in December, and Jessica's baby bump [4] has been on display throughout the past few months. Read on to see another picture of Justin's birthday celebration, and then relive all the times JT gave you tunnel vision [5].

The parents-to-be captured the moment during their snow-filled getaway. Justin shared a picture of their vacation spot in an Instagram he posted earlier this week, writing, "This view... Perfection."
