Cameron Diaz has dated several celebrities, but never thought she'd get married until she started dating her now-husband, Benji Madden, in May 2014. "[Marriage] was the biggest thing I've done in my 40s, and it opened me up in different ways," Diaz told Harper's Bazaar in May 2016, 16 months after she and the rockstar tied the knot. "It's pretty awesome. I didn't think it was something I'd do, and I don't know if I'd have done it if I hadn't met my husband. It was a surprise." While the duo's relationship was unexpected, they quickly became one of Hollywood's strongest couples.
