Watch out, Jessica Simpson. Hubby Nick Lachey is about to move in with two women, and one of them is ''Showgirls'' and ''Bound'' femme fatale Gina Gershon. According to the Hollywood Reporter, Lachey has signed on to costar in ''Hot Mama,'' the ABC sitcom pilot that stars Gershon as a free-spirited wedding planner who embarrasses her straitlaced daughter. Lachey would play a struggling actor who boards with the two women, paying his way by serving as their handyman.
ABC apparently can't get enough of Lachey and Simpson. The ''Newlyweds'' stars both have development deals with the network. She's got her own ABC sitcom, as a pop culture notable named ''Jessica Sampson'' who gets a gig at a ''20/20''-like newsmagazine. And the pair will host their own '70s-style variety show on the network on April 11.
