Mariah Carey

R&B superstar Mariah Carey has been summoned to replace flu-ridden Janet Jackson on "Saturday Night Live." The comedic show will broadcast on the March via NBC. Jackson, 41, was scheduled to perform live Saturday night in support of her latest album, "Discipline," which was released last month. The singer's publicist, Patti Webster, said Tuesday she dropped out because she has the flu and "needs some time to get better." Carey's latest album, EMC2, arrives April 15.
