Backstreet Boys Perform "Don't Go Breaking My Heart," Prove They've Still Got It Going On

Backstreet Boys are back, and we couldn't be happier. The group has been busy promoting their new single "Don't Go Breaking My Heart," and on Thursday night they gave a special performance of the song on The Tonight Show Starring Jimmy Fallon. After joining the host and The Roots for a special classroom instruments session of "I Want It That Way," the '90s boy band proceeded to make our hearts melt with their slick dance moves and swoon-worthy voices. Whether they're performing or adorably surprising fans in elevators, they still make us feel like lovestruck teenagers.
