FREDDY VS. JASON Maybe she's not such a survivor: Looks like Kelly Rowland's destiny now lies in the razor-sharp hands of Freddy Krueger (''Nightmare'' vet Robert Englund). On Aug. 15, the Grammy winner makes her film debut as Kia, a dream-deprived Elm Street teen caught up in a demonic duel between the scar-faced cranky-pants and hockey-masked Friday the 13th bad camper Jason Voorhees (Ken Kirzinger). ''The funny thing is that I'm the biggest scaredy-cat,'' says Rowland, 22. ''On set, I couldn't watch or hang out with Jason because his mask was just too freaky.... I must have old childhood issues.''
