Dinah Books Kathy Najimy Mo Gaffney

Following up their announcement that they booked pop tart Ke$ha, the organizers of Club Skirts: The Dinah want to spread word that comedians Kathy Najimy (left) and Mo Gaffney will also perform at the Palm Springs, Calif., lesbian festival.

Najimy (Veronica's Closet) and Gaffney (Absolutely Fabulous) last performed together during The Kathy and Mo Show, which ran off-Broadway in 2005. The comedians replace Rosie O'Donnell, who recently canceled her performance at the Dinah, which runs March 31-April 4.

Also attending the party will be L Word actress Sarah Shahi, who portrayed Carmen on the Showtime drama.
