Jennifer Lopez started crying and fled the stage after doing an acoustic version of "If You Had My Love" as part of the Mohegan Sun's fifteenth-anniversary celebration this weekend. (Here's a video of her performing, but it ends before she allegedly fled.) After introducing the track as "the first song I wrote about love," Lopez — who, as you might recall, just went through a pretty major breakup — launched into a performance that seems pretty much designed to cause a breakdown: "As Lopez sang, pairs of dancers appeared in spotlights around her — each portraying the American Idol judge and one of her former lovers, including Diddy, Cris Judd, Ben Affleck and Marc Anthony." By the end, she was "sobbing" and, after taking a brief break offstage, ended up cutting the set short. "Everyone was so sad for her," said an observer. "It was really dramatic." Sounds about right.
