Kelly Osbourne will make a cameo appearance in ABC's forthcoming remake The Muppets' Wonderful Wizard of Oz, TV Guide Online has learned. The soon-to-be-unemployed Life as We Know It star, playing herself, will bump into Dorothy (Ashanti) while in Oz. "It's going to break the fourth wall with the viewer," says an ABC insider. "Dorothy will say something like, like 'Kelly?'" And Kelly will have some witty comeback." The telepic is slated to air in May. In the meantime, check out the Nov. 21 issue of TV Guide magazine (on sale 11/18) for an exclusive first look at Kermit as the Scarecrow and Miss Piggy as Glinda, the Good Witch of the North.
