Taylor will be taking the stage as a presenter, along with two other new line-up additions: Teenage musical heartthrobs Austin Mahone and Cody Simpson. The trio join previously announced guests like Glee's Naya Rivera and Pretty Little Liars' Lucy Hale.
Meanwhile, three new performers have also been added to the ceremony: pop-punk outfit Marianas Trench, rap-rockers Down With Webster and EDM all-star Armin Van Buuren—who will be joined by former soulDecision singer Trevor Guthrie.
Oh, and did we mention that Psy is co-hosting the entire show in addition to playing it?
