J-Lo, doesn't like closet cases?

August 7, 2006 -- JENNIFER Lopez isn't saying why she suddenly left the cast of "Dallas" - but an industry insider tells the Post in NY, there are two very big reasons - a subpar script and the less-than-strapping John Travolta, who was to play J.R. Ewing opposite J.Lo's Sue Ellen. "The script sucks," our source says. "And John Travolta? If it had been a man's man like Ed Harris or Tommy Lee Jones . . . but you don't just go from doing 'Hairspray' to 'Dallas.' "

I"m not sure what J-Lo's problem is, KAtie Holmes seems more than happy with her great non-gay scientologist.
