When Carrie Underwood brings her Cry Pretty 360 Tour to the Cajundome in Lafayette on September 22nd there will be a special guest performer on stage with her -- YOU!

Actually, for the whole tour, she'll be inviting fans to perform with her on stage for one song. You won't be singing but rather rapping because the song is "The Champion".

One lucky fan will be doing the Ludacris rap part of the song while Carrie will handle the vocals.

If you're interested, you'll need to submit a video of yourself doing the entire rap and fill out some details.

Carrie also wants to know who your champion is and why you want to honor them. Plus, you have to submit photos of that champion.

Complete details are at CarrieUnderwood.fm/ChampionContest.
