The show must go on! Well, when it comes to J. Lo's life, that is...

Jennifer Lopez performed at the Bell Center in Montreal on Saturday night, and the 42-year-old singer/actress tore it up onstage as she danced around in a skimpy and sparkly jumpsuit.

On Friday she confirmed her departure from American Idol after two seasons, and she stated that she left because wanted to focus more on her music career and her twins, Max and Emme. While she made $12 million for the first season of the hit Fox show, she was reportedly bumped up to $15 million last season but that still wasn't enough! Rumors were swirling that J. Lo asked for a $17 million paycheck, and after Fox turned her down she decided to leave, but she swears it was never about the money. I guess her love really don't cost a thing!

P.S. It doesn't matter if it's the front or the back, she's definitely still got it:
