The Backstreet Boys "Good Morning America" reunion shows that the guys haven't aged ONE BIT.

2012 has been, like, THE BEST YEAR for boy band reunions! First, 98 Degrees melted our hearts on a recent "Today" show performance, and now Backstreet's back (ALRIGHT!) for a "Good Morning America" concert. And while our voices have gone completely hoarse from singing BSB's hits in the office (not to mention holding an impromptu *NSYNC vs. BSB tug-of-war), we still found time to gather a few of our favorite photos of the morning. How could we even possibly pick favorites, you ask!? So you don't have to hyperventilate (kinda like how our very own T. Kyle MacMahon hyperventilated out in the crowd. See below.)

Check out more photos of the Backstreet Boys' "Good Morning America" performance after the jump!

We can't stop drooling over Nick Carter holding a guitar. Remember that time he dated Paris Hilton?!

All five of The Backstreet Boys -- Nick Carter, Brian Littrell, AJ McLean, Kevin Richardson, and Howie Dorough -- appeared on "Good Morning America" to celebrate the band's 20-year reunion (::hits head on desk::) with flawless performances of "I Want It That Way" and "Larger Than Life." The guys nailed both hits, but we wouldn't expect anything less (they've had a lot of practice since touring with New Kids On The Block this past summer).

AJ McLean got "Everybody" pumped. The man's STILL got it.

Not only did AJ drive the fans crazy with his stage presence (per usual), he also spilled the beans in an interview about THEIR NEW ALBUM. (!!!) Then he dropped the biggest nugget of news yet: The gents will host a Backstreet Boys cruise in October 2013! Wait, there's going to be a shirtless boy (um, man?) band AND umbrella drinks -- we can't even. AHOY!

In case you were wondering if Nick Carter was still hot -- he is.

OMG (!!!) the boys can still do the classic boy band pose.
