Backstreet Boys And New Kids On The Block Team Up!

Epic!
Check out this AMAZEBALLS video of the New Kids On The Block performing at Radio City Music Hall this past weekend, where the Backstreet Boys joined them on stage for a surprise performance of I Want It That Way!
Look at the two different generations of fangirls losing their shiz all over the place! All they need now is a dose of Bieber fever and reality would just implode!
Unreal!
Thoughts??
