In an appearance on Ellen DeGeneres show, Lopez, 45, also slammed rumours that she is dating her 27-year-old co-star from the movie.
"I'm not after younger guys. If younger guys like me then that's one thing," Lopez said.
She drew attention to gender double-standard surrounding the term "cougar" and its lack of a male equivalent.
"There's like guys who just go after younger women. They have no name. No label," she said.
