HER QUALIFICATIONS J. Lo proved she could kick butt as a federal marshal in ''Out of Sight,'' a bitter cop in ''Angel Eyes,'' and a vengeful wife in ''Enough.'' The falling-in-love-with-Affleck part shouldn't be too big of a stretch, either.

FUN FACT After shooting wrapped last spring, Affleck bought ads in Variety and the Hollywood Reporter praising his then-married costar for her ''kindness, dedication, diligence, humility, graciousness of spirit, beauty in courage, great empathy, astonishing talent, real poise and true grace.''

WHAT'S NEXT The former Fly Girl is teaching Richard Gere how to foxtrot in the remake of the Japanese hit ''Shall We Dance?'' (now filming). Her next release, around Christmas, is the family drama ''An Unfinished Life,'' followed in February by her turn as Affleck's wife in Kevin Smith's ''Jersey Girl.''
