Seems Lopez can spot a scientology cloaked gay man just like the rest of us...

JENNIFER Lopez isn't saying why she suddenly left the cast of "Dallas" - but an industry insider tells us 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.' "
