Cameron Diaz has a message for all the single ladies: Don't get fixated on marriage.
"A lot of people chase after it because they've been told, ‘This equals happiness.' They chase it, they get it, and they find out, ‘Why did I think this was going to make me happy? I'm miserable!'" she shares in the May issue of InStyle magazine, adding: "I don't know if anyone is 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."
