The superstar, who performed an acoustic version of her first song “If You Had My Love” told the audience what she feels about romance.
"You want to talk about love? An emotional Lopez said. “I can talk about love. Oh, the stories!"
As she began singing “Until it Beats No More” lookalikes of exes Diddy, Ben Affleck and Cris Judd came on stage.
"I took a trip down memory lane," said a teary-eyed Lopez, after finishing the song. Tears running down her cheeks, Lopez than walk off stage to compose herself.
Lopez and Marc Anthony ended their marriage, in July.
The A-list celebrity couple, who have 3-year-old twins, said in a joint statement that their seven-year marriage was over.
“This was a very difficult decision,” the statement said. “It is a painful time for all involved. And we appreciate the respect of our privacy at this time.”
The couple married in 2004. They tied the knot less than a week after his divorce with Dayanara Torres was finalized.
It’s Lopez’s third marriage, his second.
