Jennifer Lopez has no limits in new song from movie "Second Act"

Sony Music Masterworks She debuted it last month at the American Music Awards, but now Jennifer Lopez has released her new single.

“Limitless,” written by Sia, is from the soundtrack of J-Lo’s new movie Second Act, in which she plays Maya, a 40-year-old woman stuck in a low-paying job. When a private finance firm is fooled into thinking she’s a high-powered consultant, it hires her to handle a major business deal and she finally gets a chance to shine.

The song is an empowering anthem, as J-Lo sings, “I told myself I had to be a different someone/In order to win at a war I had already won/Yeah, I’d given up on the saying ‘I’ll never give up’/But look at me now/Yeah, look at me, I’m limitless.”

Second Act also stars J-Lo’s real life BFF Leah Remini, as well as Vanessa Hudgens and Milo Ventimiglia. It arrives in theaters December 21.
