London-born Minnie does not deserve to be this unlucky in love, say friends

And it seems Minnie Driver faces heartache again after her fiancé left her for fellow actress Cameron Diaz.

The London-born star of Good Will Hunting seemed to have found her man, when back in September, American TV magician Criss Angel proposed to her after a romantic holiday in Mexico.

But on Monday night, Angel was spotted arm-in-arm "cuddling and snuggling" with Charlie's Angel actress Diaz.

Angel and Miss Diaz made no attempt to hide their affection for one another during a romantic dinner at the Prime Steakhouse in Las Vegas.

And after dinner the couple travelled in style, taking his Rolls Royce to the Mirage hotel, where they watched the Beatles-inspired Cirque de Soleil show, Love.

An onlooker told The Mail: "They were very obviously a couple enjoying a great date. He kept making jokes and she was giggling all the time. They were cuddling and snuggling and he kept whispering in her ear – they looked very happy together."

But while Angel and Miss Diaz were the picture of happiness, Miss Driver is said to be devastated after being jilted for the third time.

One close friend admitted: "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.

"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."

Miss Driver, the daughter of multi-millionaire insurance broker Ronald Driver, enjoyed a privileged upbringing which saw her educated at £24,000-a-year Bryanston School in Dorset, and attend finishing schools in Paris and Grenoble.

But although her acting career has been a great success, she has endured a miserable love life.

She fell in love with Matt Damon, her co-star in Good Will Hunting, and the two appeared to be heading for the altar, but then, without warning, Damon appeared on Oprah Winfrey's chat show in the US and announced live on television that he was dumping her.

Then in April 2001 she officially announced her engagement to actor Josh Brolin, but just six months later she was once again left heartbroken as the relationship broke down.

Miss Driver later blamed the split on interference from Brolin's mother, Barbra Streisand.

Before her engagement to Angel last September she also had an ill-fated fling with tennis star Robbi Ginepri.

"She is trying so hard to find Mr Right but she always seems to pick Mr Wrong," admitted a friend.

But Miss Driver's loss is Miss Diaz's gain, as the voice of Princess Fiona in the Shrek movies has moves on with her own love life after splitting from pop singer Justin Timberlake back in January.

Miss Diaz, who has had a chequered lovelife herself, was only meant to be in Las Vegas for the weekend - but apparently extended her stay after meeting her new man Angel at a party she had attended with her best friend and fellow Charlie's Angel star, Drew Barrymore.
