Mark your calendars for November 22, guys! The 2015 American Music Awards are on the way. Jennifer Lopez will host the star-studded event at the Microsoft Theater in Los Angeles, California. That's enough to get our attention, but have you even considered the performances?

It has just been announced that Demi Lovato, Nick Jonas and Walk the Moon will take the stage and we couldn't be more stoked.

The best part? It means they're joining One Direction (who've promised to perform this latest single, "Perfect,") 5 Seconds of Summer, Selena Gomez and Carrie Underwood. If only we could convince them all to perform together.
