Jennifer Lopez

R&B singer/actress Jennifer Lopez has abruptly quit the much-anticipated big screen remake of classic 1970s show ?Dallas.? The I?m Real singer was set to star opposite John Travolta--who will play J.R. Ewing--as his alcoholic wife Sue Ellen.

Lopez's representative Leslie Sloane Zelnick confirms to Star, "She is out of Dallas."

This isn't the first report of trouble regarding the film. Earlier this year, legally Blonde director Robert Luketic quit the project citing "creative differences" and was reportedly unhappy with casting choices.

?Bend It Like Beckham? director Gurinder Chadha is now awarded to direct the film.

The role of Lucy Ewing has also been the subject of much speculation, with many of Hollywood's top young actresses vying for the part including Jessica Simpson, Lindsay Lohan and Kristin Cavallari. The role ultimately went to 19-year-old Katie Cassidy, who stars in family drama ?7th Heaven.?
