"It's the first time I really got the vulnerability, the feeling of being exposed," she said. "But I pulled my G-string up and did what I had to do as an actress. This is my job, what I signed up for. I felt the empowerment and being in control of the room. There was a before and after that was drastic, from total terror to total happiness. It was hard, scary – but awesome."
She also revealed that during shooting she thought, " 'F*** it. I'm gonna be uninhibited and unafraid every day'."
To this end the 50-year-old mum of two made sure audiences were aware that she was actually doing the routines and not using a body double.
"When I went upside down (on the pole) I said, 'Please get my face, I don't care if I look like a bat hanging upside down, I want people to know there's no doubles in this movie'."
Lopez also dismissed rumours that she did and co-star Constance Wu did not get along.
"I love her. It was a special movie. I felt like there was a matchmaker at play. It was a safe place because we kind of let the love happen to us. We have to get pretty close (in the movie) so we had lots of conversations about butt-grabbing, asking 'Are you OK?' We had to get in a teasing mentality with each other."
