Jennifer Lopez says she's a huge "Glee" fan and would love to guest star on the show -- but unfortunately, it's just not in the cards right now.
In an interview with Ellen airing today, the "Back-Up Plan" star says it all comes down to scheduling conflicts: "I sat down with ["Glee" creator] Ryan Murphy and we talked me doing something ... but it doesn't fit in."
But according to J.Lo, that doesn't mean it won't happen down the road -- and says she told Murphy "I'm a huge fan whenever you want ... I kind of offered myself up."
