Jennifer Lopez — My Grudges Are Gone, Girl

Jennifer Lopez is all about her ex-boyfriends this week … first she hung out with Diddy at a nightclub — then she tartan out her ex-fiance Ben Affleck‘s hit movie, and existing some weird proof.

Lopez went to see “Gone Girl” Saturday night … which we know because she posted a pic of her feet up in the theater with the heading, “#GONEGIRL.” Weird, but maybe her booty isn’t the only thing fans dig. 

As we previously reported … Diddy reunited briefly with J.Lo at Hooray Henry’s this week.

Cris Judd … Casper Smart — keep your dance cards open.
