Jennifer Aniston debuted her pipes on The Ellen Degeneres Show yesterday in advance of her role in the all-girl prison band musical The Goree Girls, currently in pre-production.

If I'm being honest, Jen wasn't that great - but certainly good enough to star in a movie-musical (if we're judging by Mamma Mia standards), but Ellen said she'd put Jen into the next round on Idol!

Well, maybe if they ever have an over-40 Idol, Jen will have her chance to be called "pitchy" by Randy and be chewed out by Simon!
