Ricki Lake is busy developing a new talk show, chatting about her love life in the press and writing her life story -- a new book deal will have her memoir on shelves next spring. But there's one chapter in her life she probably doesn't want to talk about.

Lake is now being sued by Hovsep Kousayan, the owner of a house in Malibu, Calif., that the TV star and her family rented last year.

The beachfront home was destroyed by a massive fire in September, which allegedly began after Lake spilled oil while refilling a space heater.

The lawsuit, according to a report by TMZ, was filed in a Los Angeles court earlier this week. Damages sought could be in the millions.
