JLoBreaksDown230.jpgJennifer Lopez took an emotional trip down memory lane at her concert Saturday night.

The 42-year-old diva took the stage in Montville, Conn., to sing "If You Had My Love." She introduced her hit with, "You want to talk about love? I can talk about love. Oh, the stories!"

After singing it, she concluded: "That's the first song I wrote about love. And this is the last song I wrote about love. A lot has happened since then."

Then, Jen belted out one of her new tunes, "Until It Beats No More," and several male dancers took the stage -- dancers who looked a whole lot like her famous exes, including P. Diddy, Chris Judd, Ben Affleck and Marc Anthony.

After, Jen explained to the crowd, "I took a trip down memory lane." The camera zoomed in on her, and the audience could see that the American Idol host was tearing up!

But, Lopez is clearly persevering. As the jam-packed crowd broke into supportive applause, J. Lo held up a picture of her twins, Max and Emme, and declared: "There's love -- and then there's love."
