demilovato230clear.jpgWhile we'd love to hear Demi Lovato has signed on for some weighty movie roles following her pending exit from rehab, it looks like Marvel's The Avengers will definitely not be one of them.

Reports spread early Wednesday claiming the troubled Disney star was "up for the role" and then "in it", but sources close to both Lovato's and Marvel's camps quickly denied the actress had any involvement with the film.

The Avengers promises to be a mega-hit with a star studded cast set to reprise their popular Marvel comic characters, but the studio is looking for an additional female lead to break-up the almost all-male cast. It would be a great opportunity for Lovato, but since she is currently in rehab “for emotional and physical issues”, there is no possible way she can join a film slated to shoot spring 2011.

As of now, the cast list includes: Scarlett Johansson (Black Widow), Don Cheadle (War Machine), Robert Downey Jr. (Iron Man), Samuel Jackson (Nick Fury), Jeremy Renner (Hawkeye), Chris Evans (Captain America), Mark Ruffalo (Hulk), Chris Hemsworth (Thor), and Lou Ferrigno will return as the voice behind Hulk.

The female role Marvel is looking to fill has yet to be revealed.
