Lopez reportedly tears up onstage in Conn.

Jennifer Lopez reportedly teared up at her Mohegan Sun concert Saturday when a stage routine re-enacted scenes from past romances, using look-alikes of herself and four exes -- including third husband Marc Anthony, from whom she separated in July.

"You want to talk about love? I can talk about love. Oh, the stories!" she told the audience at the sold-out venue in the Montville, Conn., casino-hotel, according to Us Weekly. She then launched into her first number-one single, "If You Had My Love" (1999). Then, said Us, she told the crowd, "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!" People magazine reported it differently, quoting, "I'm going to sing you the last song I wrote about love. A lot has changed since then."

Both magazines say that Lopez, 42, then performed "Until It Beats No More." However, she did not write that song -- and Hartford Courant music critic Eric R. Danton, who attended the show, said in his review that Lopez in fact sang "One Love," which she did cowrite.

Us and People, regardless, each described a stage routine in which a Lopez look-alike danced with performers meant to evoke hip-hop star Diddy, whom Lopez dated for 2 1/2 years in the 1990s; backup dancer Cris Judd, to whom she was briefly married; actor Ben Affleck, to whom she was engaged from November 2002 to January 2004 before splitting up; and Anthony. (First husband Ojani Noa apparently didn't rate.)

When the song ended, said Us, Lopez told the crowd, "A little trip down memory lane," and then paused and looked down; a camera zooming in showed her eyes welling up, to which the audience gave a standing ovation. People quoted instead, "I took a trip down memory lane," and mentioned simply applause; it also said she then held up a photo of her 3 1/2-year-old twins, Max and Emme, and said "There's love -- and then there's love."

The Courant critic -- who made no note of the reported emotionalism -- said Lopez then left for a costume change, and ended the 70-minute show with a three-song finale.
