Jennifer Lopez threw on her sequined catsuit Saturday for a show at the Mohegan Sun casino's 15th anniversary extravaganza. She was at the Uncasville, CT, location a few days earlier to debut her Jennifer Lopez for Kohl's collection as well. J Lo covered up her one-piece ensemble at the start of her show with a blazer from the Rachel Zoe Collection. She wasn't wearing the jacket, though, when things got emotional on stage. Jennifer Lopez cried about Marc Anthony, her estranged husband, during one number. Jennifer's romantic medley "Until It Beats No More" was apparently a tribute to Marc and her other great loves, Diddy, Cris Judd, and Ben Affleck. She referred to the track as a, "trip down memory lane." She added, "I'm going to sing you the last song I wrote about love. . . . A lot has changed since then."
