Jennifer Lopez shocked fans, laying her emotions bare during a performance at the Mohegan Sun Arena's 15th anniversary celebration on Saturday night.
An onlooker tells ET that the pop diva became emotionally overwhelmed after walking the crowd through her past love life, saying that J.Lo broke down in tears when the audience went wild.
J.Lo sang such hits as If You Had My Love, One Love and Until it Beats No More. At one point she even had dancers accompany her lookalike on stage who resembled her exes Diddy, Cris Judd, Ben Affleck and Marc Anthony. The J.Lo and Marc doppelgangers recreated the former couple's sexy number at the American Idol finale.
This performace comes just months after the singer, 42, split from Marc after seven years of marriage.
