Newsflash: A newlywed thinks having lots and lots of sex is a glorious thing. That newlywed is Cameron Diaz, who married rocker Benji Madden in January. Apparently, those two are still enjoying their honeymoon phase, because the actress couldn't resist speaking out about her favorite hobby in Cosmopolitan U.K.'s Love Your Body issue, out now. "It's something healthy that we need to be doing for many different reasons," Diaz told the mag. Let us count 'em! As you may have guessed from the body-image book she put out last year, the 42-year-old star is something of an exercise nut. Her advice to the rest of us is simple: "Just do it." "Once you commit and really put in the effort, your body goes, 'Oh, it's not okay to be without this,'" Diaz said. "People say, 'My body rejects exercise.' No, it doesn't. Your mind rejects exercise." But, wait. Sex counts as exercise, right? Because, we can get down with that.
