Zac Efron [1] had Sami Miro by his side to celebrate his wins at the MTV Movie Awards on Sunday night. Although the couple didn't walk the red carpet together, Sami posted a cute backstage snap [2] on Instagram. She wore a short, long-sleeved black dress to the show, and Zac was all smiles with his arm around her in the photo. The pair's date night came just a few weeks after Sami opened up about their blossoming relationship [3] in an interview with Elle, saying of his fame, "I've never spoken about us before, but, um, it's definitely different. I think that you have to take that [kind of attention] with a grain of salt, and put yourself in other people's positions. I think that's actually a really big part of it, putting yourself in their shoes, and trying to understand where they're coming from, and then it kinds of makes sense."

Sunday's award show was a fun night for Zac, who was among this year's MTV Movie Award winners [4]. He took home the award for best shirtless [5] performance thanks to his role in Neighbors, plus best duo with his costar Dave Franco. Once again, Zac went shirtless [6] during the show, and at one point, Dave joined him on stage to re-create their Robert De Niro scene [7] from Neighbors. Check out the sweet snap of Zac and Sami, then see pictures of their recent Mexico getaway [8].
