Mariah Subs for Ailing Janet

Mariah Carey to the rescue!

Mimi will step in for Janet Jackson on Saturday Night Live this weekend after Miss Nasty herself pulled out of the March 15 show due to the flu.

The appearance will mark Mariah's first return to the sketch show in 10 years, and it comes at a perfect time. The 38-year-old's new album E=MC2, which features her seductive single "Touch My Body," hits shelves Apr. 15.

Superbad's Jonah Hill is the scheduled host on SNL.
