Who's on deck this year to ring it all in with Mr. Seacrest? Camila Cabello, Nick Jonas, and Sugarland will be on the bill for this year's festivities, according to E!, while Ciara will help out with the LA crowd. Though the lineup will expand for sure, we will have to wait to see the FULL lineup announcement. My guesses for who's to come? Charlie Puth, Hailee Steinfeld, Bebe Rexha, and Florida Georgia Line. Amy Cooper is one with the force and the force is with her.
