One Direction Explains Their Miley VMA Reaction

ET's Rocsi Diaz was with One Direction for their big One Direction: This Is Us movie premiere in New York City Monday night, where the boys elaborated on the much-shared photograph of themselves and Rihanna reacting to Miley Cyrus' racy MTV Video Music Awards performance, which quickly went viral.

"It was interesting, yeah," Liam Payne said about Miley's controversial twerking.

"You just can't hide that, can you?" he added, explaining their priceless facial reactions in the photograph.

The boy band also showed some love for Lady Gaga, who was caught on camera giving them a pep talk backstage after some audience members booed during their acceptance speech for Song of the Summer, which they won for their hit Best Song Ever.

"It's gotta be coming off stage and getting some advice from Lady Gaga," Louis Tomlinson said about what they view as the craziest thing that's happened to them in NYC. "We just came off stage and she was there, and she just said some pretty nice things. I don't know, it was just really cool to hear."
