Jennifer Lopez is definitely coming back to "American Idol!" ... to perform.
Citing an unnamed source, E! News reported Wednesday that the former "Idol" judge will perform on next month's season finale.
No word yet on whether she'll appear on the first or second night of the two-part finale on May 15-16.
Rumors began swirling last week not only about a J-Lo performance, but the possibility that she may be coming back as a judge, possibly replacing Mariah Carey.
"There will definitely be changes to the judging panel for next season," a source told E! News last week. "Fox thought the Nicki (Minaj)-Mariah contrast would make for ratings, but there is concern it is like nails on a chalkboard for middle-America viewers."
Of course, a rep for the show said, "This is just another ridiculous 'Idol' judge rumor, likely started by talks of Jennifer performing on the finale."
Who would dare say the words "ridiculous" and "American Idol" in the same sentence?
An "Idol" rep declined to comment on Lopez's upcoming performance.
