The World of Dance judge was a guest on Jimmy Kimmel Live! on Wednesday, where she revealed she is learning how to pole dance for the upcoming film Hustlers, in which she portrays a stripper.
"This is true," Lopez, 49, said. "That is not a rumor!"
And it sounds like her boyfriend, former MLB star Alex Rodriguez, is getting a front-row seat to all her practice sessions.
"We do have a pole at the house right now," Lopez shared, joking that they'll also be going to some strip clubs together for research. "It's a portable pole. First of all, this is gonna go bad... but you can practice with it there. I have a girl who comes in and teaches me."
"It's very hard," she continued. "It's a girl from Cirque du Soleil. She's fantastic and she works with me and, I mean, I have bruises everywhere. It's so hard. I have a lot of respect for people who do the pole. It's, like, acrobatic. It's different muscle groups and the things they do with their legs, upside down, I'm like, 'What? I can't... hold on. Can we do that part again."
Later in the interview, J.Lo revealed that the film is based on a true story about a group of women from the Scores strip club in New York who "took a bunch of Wall Street guys for a bunch of money."
In addition to all her hardcore pole dance training, Lopez also went on a 10-day no sugar, no carbs diet to prepare for the role (and her epic GRAMMYs performance). Rodriguez also participated in the challenge as a way to support his girlfriend, and needless to say, it looks like all their hard work paid off:
