On hand to help the venue celebrate its 15th anniversary, J-Lo enlisted background dancers resembling her famous exes -- Diddy, Cris Judd, Ben Affleck and Marc Anthony -- to perform during the song 'Until It Beats No More.'
The dancing dopplegangers interacted with a Lopez lookalike, and when the singer herself took the stage, she appeared overcome with emotion.
"I took a trip down memory lane," a tearful Lopez said, evidently responding to the faux Anthony. The Bronx-born singer, dancer, actress and TV star announced her split with the real Anthony in July after seven years of marriage.
The 'I'm Real' singer then ran offstage, marking one of two times in Saturday's show that she would get, well, "real" with fans. At another point, following an acoustic rendition of 'If You Had My Love,' she took a moment to pose a philosophical question.
"What is love?" she asked the audience. "As the last song I wrote about love ... a lot has changed since then."
One thing that hasn't changed: the healing powers of a good Fat Joe collaboration. The rotund rapper joined J-Lo for the 1999 jam 'Feelin' So Good,' sending an unspoken message about taking the good with the bad.
