Justin Timberlake has lots to celebrate this year. Not only is he ringing in his 34th birthday, but he is also going to be a dad!

OK, OK. We know that rumors have been circulating for a while now that wifey Jessica Biel was pregnant with their first child.

And sure, fellow *NSYNC-er may have spilled the beans on the news. But nothing says it's official till there's a pic on Instagram. "Thank you EVERYONE for the Bday wishes! This year, I'm getting the GREATEST GIFT EVER. CAN'T WAIT. #BoyOrGirl #YouNeverKnow #WeDontEvenKnow #WeAreTakingBets," Justin captioned the photo of himself and Jessica.

Now isn't that one of the sweetest pics you've ever seen? We're definitely gushing on this side of the interwebs.

Congratulations to the soon-to-be new parents!
