It comes with the territory! Cameron Diaz opened up about her husband, Benji Madden, and the worst thing about marriage during The Ellen DeGeneres Show on Thursday, May 5."Someone asked me, 'What’s your favorite thing about being married?' And I was like, 'Well, I just learned so much about myself. I didn’t know these things.' And I was like, 'I would have never known them if I didn’t meet my husband, who helped me,'" Diaz, 43, told host Ellen DeGeneres.
