Miley Cyrus isn’t the only big name act performing at the 2013 American Music Awards. Airing on Sunday, November 24, the AMAs will also feature the likes of One Direction, Justin Timberlake, and Rihanna. Also taking the stage? Up-and-coming star Ariana Grande.

The 20-year-old star of Nickelodeon’s Sam & Cat announced the exciting news via her Twitter, telling her millions of fans, “I’m also so excited to announce that I’m going to be singing on the #AMAs this weekend! So honored and so nervous... but going to be so fun!”

We already have our guesses as to what Disney princess Miley will get up to at the AMAs, but what might Ariana have in store? Perhaps a duet with her boyfriend, Nathan Sykes of The Wanted, or could she push the envelope and give a little twerking a try?

Ariana has, after all, been a vocal advocate of Miley, recently telling Complex magazine that people should just “shut up” about the “Wrecking Ball” singer’s questionable antics.

Better than another round of twerked out entertainment would be Ariana performing the song Miley hinted she wrote for the pop star...while showering. We’re thinking giant rubber duckies and dancers in shower caps for Ariana’s big AMA performance. Oh and maybe a loofah or two.
