Is Jennifer Lopez's 'Glee' back-up plan still on?

jennifer-lopez-glee.jpg"Glee" fans, rejoice. If you also happen to be a Jennifer Lopez fan, that is. If not, The Dish Rag is sorry in advance.

Word is that "The Back-Up Plan" star is still hoping (maybe even praying) for a guest role on the hit FOX show, especially after her latest rom-com tanked big time on its opening day.

She told Ellen DeGeneres Friday (Apr.  23) on her talk show, "I sat down with [show creator] Ryan Murphy and we talked about me doing something on "Glee." We want to. We want to do it."

As for timing: "They have it all mapped out for the next like eight episodes," she says, "whatever is airing right now. So he's like let's wait and do it really right when you do come on."

Murphy has said he wants Lopez to play a cafeteria lady at McKinley High who gets glammed up by Chris Colfer's character Kurt Hummel.
