NEW YORK  —  "Saturday Night Live" has replaced a flu-ridden Janet Jackson with another diva: Mariah Carey.

Carey, 37, will fill in for Jackson on the March 15 "SNL" telecast, NBC announced Wednesday.

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.
