It was an emotional night for Jennifer Lopez: The singer broke down while performing a song about lost love at the Mohegan Sun's 15th anniversary celebration. "I'm going to sing you the last song I wrote about love," she told the crowd in Montville, Conn. "A lot has changed since then."

J.Lo then performed "Until It Beats No More" while dancers re-enacted scenes from the singer's life -- complete with guys who looked an awful lot like her exes, P. Diddy, Chris Judd, Ben Affleck, and her estranged husband, Marc Anthony. When the song ended, she said: "I took a trip down memory lane," then cried as the audience clapped. Then she received a standing ovation.
Love seemed to be the theme of the evening. Before breaking out an acoustic rendition of "If You Had My Love" she told the crowd: "You want to talk about love? I can talk about love. Oh, the stories!"On a lighter note, the singer held up a picture of her young twins during the show, and said: "There's love – and then there's love."
