Lopez opened up about her experience in Hollywood in an interview to Harper's Bazaar magazine, reports nydailynews.com.
She said that she was made uncomfortable by inappropriate demands from a director asking her to show her chest.
"I haven't been abused in the way some women have. But have I been told by a director to take off my shirt and show my b**bs? Yes, I have," Lopez said.
"But did I do it? No, I did not," she added.
Lopez says she was terrified to come forward about the experience, which occurred on one of their first meetings.
"When I did speak up, I was terrified. I remember my heart beating out of my chest, thinking, 'What did I do? This man is hiring me!' It was one of my first movies. But in my mind I knew the behaviour wasn't right. It could have gone either way for me."
She did not reveal the name of the director.
