A source tells Us Weekly that Lovato, 20, and Horan, 18, headed to Pink Taco after the awards show grab a bite to eat -- just the two of them! The two stars have been rumored to be dating after Lovato admitted in an interview earlier this year she thinks Horan is "adorable." In June, Horan's bandmates picked Lovato as his perfect match during a round of "Rapid Fire Romance" on etalk. "Niall dreams dirty things!" Harry Styles teased.

Lovato won a Moonman award at the VMAs for Best Video with a Message for her hit song, "Skyscraper." One Direction, hitting the festivities for their first time, took home three awards for Most Share-Worthy Video, Best New Artist and Best Pop Video for "What Makes You Beautiful."

"Guys what the Hell! You are incredible, 3 VMAs!" Horan tweeted after the show. "We love you all so much! All 3 of them are for you! Thank you!"

While accepting his award for Best Pop Video, Horan scored a kiss during the show from a huge pop star -- and it wasn't Lovato.

"Katy Perry, looks like it's official . . . me and you," Horan tweeted with a photo of sharing a kiss on the lips. Perry, 27, replied, "I'll be your Mrs. Robinson . . ."
