Ailing talk show host Rosie O'Donnell will host Nickelodeon's Kids' Choice Awards on Saturday after all. O'Donnell — who cancelled the gig when her doctors advised her not to fly as she recovers from a staph infection in her surgically repaired left hand — changed her mind because of her "dedication to kids," the Los Angeles Times reports. Meanwhile, Sabrina, the Teenage Witch star Caroline Rhea will meet with Warner Bros. execs this week to discuss the possibility of taking over O'Donnell's talk show when she leaves next year, according to the New York Post.
