According to Shuter, one reason celebrity relationships break down is because the rules change. He says, "In marriage, most peoples' lives generally stay the same. That doesn't happen to celebrities. One movie or record can change their lives overnight." He adds, "As wonderful as those opportunities sound, it can be very hard on a partner that didn't sign up to be married to the sexiest man alive. Look at Bradley Cooper. He had a bit part on Sex and the City and then he was the star of 'The Hangover' and that's a massive change."
