The Other Woman actress made headlines after an article in the May 2014 issue of InStyle magazine, in which she said she didn't think people were "really naturally monogamous."
"We all have the same instincts as animals. But we live in a society where it's been ingrained in us to do these things," she said.
After some backlash about her comments, Diaz said her words were taken out of context.
"That's not what I said. My character says she doesn't believe in monogamy...! I believe in monogamy. That is an important part of a successful relationship," she said of her jilted character in the movie The Other Woman.
"I have had (monogamous relationships). And, by the way, also, not all relationships end because people get cheated on or people cheat. Relationships end because they end for whatever reason, but they are still successful relationships that have been monogamous for however long they've lasted," Diaz added.
