While the rumors that American Idol producers tried to replace Mariah Carey with Jennifer Lopez were quashed by the FOX PR Machine, it does appear one spoiler we've heard is true  Jennifer will return to perform on the American Idol 2013 finale.

E! News has reported that Jennifer will appear on either May 15 or May 16 episode. We wonder who will have the bigger dressing room — Mariah or Jennifer? Come on, you know you were wondering, too.

The song Jennifer will be performing has yet to be confirmed, but many are guessing it will be “Live It Up,” the first single off her next album. Like the other hit songs she performed on the American Idol stage before “On The Floor” and “Dance Again” this song features Pitbull. That should make for a lively performance!

Will Ryan Seacrest create an uncomfortably tense moment by making the two judges have an exchange during the show, or will he gloss over it like the seasoned veteran he is? Ooh, we almost can’t wait!

Who would you rather see perform on the show Mariah or Jennifer?
