Moments to look out for:
1. Will Katy Perry and Taylor Swift squash their beef for good?
Rumors have been swirling that the former frenemies will hit the stage together, proving there's no longer any Bad Blood" between the two. Perry previously denied the reports and Garret English, an executive producer from the show, told ET that "that's not happening," but we're not buying it just yet. It's the VMAs and anything can happen!
And seeing as Swift just announced that her sixth studio album, Reputation, is on its way, we wouldn't be surprised if she unexpectedly takes the stage.
"There's nothing happening [with that] right now," English said. "But wouldn't that be great?"
2. Cute moments between Selena Gomez and The Weeknd
Considering he's up for five awards, including Best Direction, Video of the Year and Artist of the Year, The Weeknd will most likely be at the show on Sunday. No word on whether his girlfriend, Selena Gomez, will be by his side (she's nominated for Best Collaboration with Charlie Puth for "We Don't Talk Anymore" and Best Dance for "It Ain't Me" with Kygo), but our fingers are crossed that the two will make their awards show debut (their first official red carpet as a couple was at this year's Met Gala). Plus, we'd love to see them dance along to the night's performers!
3. Our first sneak peek at MTV's TRL revival
TRL is officially returning to the network in October, so we're expecting plenty of teases Sunday night. The series' social media correspondents, Eva Gutowski, Gabbie Hanna and Gigi Gorgeous, will be in attendance, capturing the most talked about moments from the event.
