IMDB.com reports Jennifer Lopez angrily stormed out of a surprise lunchtime meeting with fiance Ben Affleck because she felt sure she’d wandered into a clinch between her man and his new Christina Applegate. Affleck was rehearsing a scene for new movie ‘Surviving Christmas’ with the former ‘Married… With Children’ star when he started chatting to her about her role in celebrity burlesque revue The Pussycat Dolls. But just as Applegate was giving Ben a taste of her sexy dance act, Lopez walked in on the couple, and promptly marched off. Set sources claim Affleck ran after his wife-to-be and managed to calm her down before the couple disappeared to spend some quality time together in the actor’s trailer.
