FOUR'S A CROWD FOR SJP

Note to SARAH JESSICA PARKER: Hate to bare bad news, but you'll soon find out anyway that Warner Bros. will NOT honor the "gentleman's agreement" you once had with HBO - which dictated that only your photo could appear on promo posters for TV's "Sex and the City!" Posters for the movie WILL feature all four women, say insiders. Even though Parker informed Warner Bros. of her old "agreement" with HBO, it was never part of either her TV or film contract, and the studio thinks featuring Parker as the solo star's a dumb way to market the big-budget flick. TIP: Everyone's predicting fireworks (or waterworks?) when sexy Sarah (yeah, I think she's very sexy, you Maxim mag jerks!) discovers she's a team player!
