It will be her first time as host, NBC said Tuesday. She previously appeared on "SNL" in a tongue-in-cheek interview with Jimmy Fallon on the show's "Weekend Update" segment.

Hilton is the star of "The Simple Life" (search) with friend Nicole Richie. The Fox TV reality series, now in its third season, features the duo working in a series of menial jobs.

She also has published a memoir, "Confessions of an Heiress: A Tongue-in-Chic Peek Behind the Pose."

British band Keane will perform as the show's musical guest.
