See One Direction, Jason Mraz, the Wanted, and other stars goof off backstage at Madison Square Garden
The One Direction singer enjoyed some solo time in the photo booth and then snuck off to hang out with fellow performer and rumored new girlfriend Taylor Swift. Earlier in the week, the couple packed on the PDA at a birthday dinner for one of Swift's pals. "I'm happy they're good friends," Styles' bandmate Louis Tomlinson told Us of the pair. "She's a really lovely girl."
