As sad as it may be, this was the week of the celebrity break-up. It started over the weekend with Jennifer Love Hewitt and Jamie Kennedy , and continued to celeb power couples Kate Winslet and Sam Mendes and Sandra Bullock and Jesse James . Taking all three of these break-ups together, and comparing them other past celeb break ups, a pattern starts to emerge. It seems that celebrity couples tend to break up not long after appearing together on the red carpet at a big event. Coincidence? Or a crafty bit of PR timing? For J-Love and Jamie, it was the celebration for the 100th episode of their show Ghost Whisperer , on March 1. Less than two weeks later, they were over . For Kate and Sam, and Sandra and Jesse, the red carpet was on a much bigger stage: the Academy Awards. Both couples were also spotted repeatedly on red carpets throughout the awards season this year and — for Kate and Sam, last year — with special attention paid to Sandra and Jesse, because Sandra was up for best actress honors for her role in The Blind Side . Somehow, their break up is that much more heartbreaking for fans because the couple’s sweet handholding and red carpet PDA has been splashed all over gossip rags for months. And although Kate walked the carpets solo this awards season, her marriage to Sam ended months ago, not long after she took home the Best Actress prize for The Reader . These three couples may be the current crop of celebs to fall prey to this hazard, but they are not the first to break up following a very public outing. The Oscars are a particular kiss of death. Just look at all the seemingly happy couples who have crashed and burned less than a year after one of them accepted Hollywood’s biggest prize: Halle Berry and husband Eric Benet , Julia Roberts and Benjamin Bratt , Hilary Swank and Chad Lowe , Reese Witherspoon and Ryan Phillippe , even Leo and Gisele . All those photos of couples on the red carpet should come with a warning: couples may be less happy than they appear. What are some other celebrity couples who broke up shortly after appearing happy in public? Post from: Crushable
