Man, this year’s American Music Awards are really looking to be called the “biggest awards show of the year!” It seems like every day we find out more and more about what will be going down this Sunday night in LA and it can be easy to forget who’s performing, who’ll be there, etc. To help you keep all the AMA facts straight, we felt it was appropriate to give you all a run-down on this year’s show!

It was just announced that Ariana Grande and Christina Aguilera have been added to the already massive performers line-up, with Christina teaming up with A Great Big World for “Say Something.” While we’re not sure what Ariana will be singing, we’re going to take a wild guess and say “Right There” with the possibility of Big Sean joining her.

Katy is set to open the show with her new single “Unconditionally,” while it’s rumored that Miley will close it with something that nobody is expecting. Seriously, you just never know what this girl will do anymore. Pitbull will be taking over hosting duties throughout the evening, as stars like Taylor Swift, 2 Chainz, Kristen Bell, Ciara, Fall Out Boy, Kelly Osbourne, Jennifer Hudson, Emma Roberts and more will present the awards.
