After winning Best Female Video for her anthem "I Knew You Were Trouble," Swift said at the podium, "I also want to thank the person who inspired this song because now I got one of these" -- an obvious poke at Styles.

Harry told AJ it was all in good fun. "I like a joke as much as the next guy, so it's all good." Styles even partied with Swift and her tour mate, Ed Sheeran, after the show. Harry smiled, "Yeah, I went for a drink with Ed… and some friends. It was good."

Harry also joked about Miley Cyrus's VMAs performance that has everyone talking. "I thought it was vanilla. I would feel comfortable watching it with my grandma."
