Clearing Up the Madonna Report
The latest rumor to join the crazy-New-Moon-rumor bandwagon was that Madonna may have a small part in the movie. Entertainment Weekly has clarified that this is FALSE, and that IF Madonna was to have any involvement at all, it would be in the soundtrack.
Widespread Internet chatter that Madonna may participate in some capacity in the Twilight sequel, New Moon, may be only partly true, a source close to the production tells EW. Summit Entertainment, the studio behind the movie series, has no plans to cast the pop star and sometime actor in New Moon. However, because Madonna's manager, Guy Oseary, is a producer on the project, there is some talk of her providing songs for the sequel. Still, no deals have been made yet, and the plans haven't progressed beyond the that'd be cool stage.
