Looks like after treating Jessica Simpson like nobody, John Mayer has moved on to another Hollywood star: Cameron Diaz. While she has previously said that she is not interested in a traditional marriage, she had a so-called rock solid relationship with Justin Timberlake but that didn't last. In one of the classic cases of an older woman dating a younger man, Cameron Diaz who is 35 has been dating John Mayer who is just 29. They have been publicly seen at the Bowery Hotel and Indochine in New York.

When we all thought that Justin Timberlake and Cameron Diaz had the perfect relationship, they shocked everyone by splitting. Another couple that divorced is Kimora Lee and Russell Simmons (though I still see the couple together from time to time).

In the musical chair game of Hollywood relationships, it was rumored that Cameron Diaz maybe dating Djimon Hounsou, though they claimed that they were just friends. It turns out that Kimora Lee Simmons may also be hooking up with Djimon Hounsou - they were both spotted at the Hyde nightclub.

Oh, my dear Hollywood friends; please stop the insanity.

Justin Timberlake Cameron Diaz breakup

Brad Pitt and Angelina Jolie are not married but have a strong relationship. So do Oprah and her boyfriend Stedman Graham and many other couples who often choose to live together without marriage. Many women even choose to become mothers without marriage. Justin Timberlake and Cameron Diaz also belonged to that group and there were rumors of having a child together.

In a shock to their fans, the couple ended their relationship after four years of what seemed like a perfect relationship.

What went wrong?

Since they were only dating, there are no divorce papers to look at but speculation is that there was another woman involved: Scarlett Johansson who believes in open relationships. She has recently ended her relationship with Josh Hartnett and was acting in a music video by Timberlake.

How has the couple behaved after their breakup?

Not too good. The best way to handle a breakup is to move on and be civil. On the contrary, when Justin Timberlake met Jessica Biel at a Golden Globe party organized by Prince at the Beverly Wilshire hotel, Cameron Diaz made a big scene. The couple was seen arguing in a side room. The message here is simple: once you breakup, the best thing is to be cool about it no matter what your ex does.
