Cameron Diaz’s weekend hook-up with magician Criss Angel may have been surprising to the public, but no doubt, the most surprised person was Criss’s former fiancée, Minnie Driver.

Last September, Angel proposed to Driver while on vacation in Mexico. Now, only eight months later, he was seen arm in arm with Diaz. One witness to Angel’s and Diaz’s lovey-dovey display in Las Vegas on Monday night told London’s Daily Mail, "They were very obviously a couple enjoying a great date…They were cuddling and snuggling and he kept whispering in her ear – they looked very happy together."

A friend of Minnie’s revealed that the “Riches�? star is devastated. Says the pal, "I was so happy for her when I heard back in September that Criss had proposed – she’s 37 and she was very ready to settle down and start a family before it's too late. Now I am worried that she will give up on men forever."

This isn’t the first time Driver has suffered from a broken engagement. She called off her wedding to actor Josh Brolin, who is now married to Diane Lane, only six months after announcing their engagement. And Driver is no stranger to public humiliation either. She infamously heard of her split with Matt Damon while watching him announce it on the Oprah Winfrey show.

Minnie’s friend said, "I really can’t believe this has happened to her again. It's so cruel and she doesn't deserve it, she’s a great girl but she always seems to pick the wrong guy.�?
