People magazine reports that after performing an acoustic version of her hit "If You Had My Love," Lopez told the audience: "I'm going to sing you the last song I wrote about love. A lot has changed since then."

She then launched into a rendition of "Until It Beats No More," while dancers re-enacted scenes from the singer's past relationships. According to the magazine, a Lopez lookalike danced alongside men that looked like her former loves, including Diddy, Ben Affleck, Cris Judd and Anthony.

"I took a trip down memory lane," Lopez, 42, reportedly told the crowd, before starting to cry as the audience applauded.

After the show, the singer told "Access Hollywood" why she got emotional.

"After I sang the song, I'm standing there, and I realized that I did bare a little bit of my thoughts in this song," she explained. "I also acted it out, kind of, for the audience. The way they received it was very touching."

"It was very, very touching. I think they felt that, and I felt it from them," she added. "It kind of overwhelmed me."

Lopez has 3-year-old twins with her estranged husband. Recently, she's been romantically linked to actor Bradley Cooper.
