When you're feeling fragile after a break-up, there's only one thing to do.

So after splitting from her fiance Billy Zane, Kelly Brook went home to visit her mother.

Yesterday she was seen leaving the house in Kent, with a wide smile - perhaps relieved that her tempestuous relationship with the 42-year-old Hollywood actor is behind her.

Smartly dressed and wearing heels, Miss Brook, 28, headed for the next stage in break-up therapy - lunch with a girlfriend.

It had become apparent at the Bafta awards on Sunday that the couple's four-year relationship was in trouble.

The actress appeared on the red carpet alone - and without her engagement ring.

She had already delayed the wedding date last year - and began growing tired of Zane's moodiness, friends said.

Yesterday she was spotted indulging in a spot of retail therapy, trawling through Covent Garden boutiques for shoes and dresses on her own.

The 28-year-old former Big Breakfast presenter has decided she is too young to marry.

Billy, 42, is now moving back to Los Angeles for good after moving out of their £1million farmhouse in Kent.

A source told The Sun: “After much soul-searching, Kelly decided that Billy is not the man she wants to marry and has called off the engagement.

“The split is completely amicable and the decision was made after long conversations here and in the US. They remain good friends.”

Miss Brook's rethink is said to come after the death of her father, Kenneth Parsons, in November last year. Mr Parsons, 57, died following a battle with cancer.

The actress initially hoped to continue competing in the BBC1 show Strictly Come Dancing and was one of the favourites to win.

But within days, she quit the show, saying she found it too difficult to continue.

Over: Kelly has called off her engagement to Billy Zane after four years together

The couple while filming castaway thriller Three in 2004 just after she'd split with Lock, Stock And Two Smoking Barrels star Jason Statham, 40.

They had planned to wed in a romantic ceremony at their 600-year-old Kent home.

Last month, she scotched rumours that there were problems in the relationship, saying: “We hope to get married soon, maybe this year."

A friend of Titanic star Zane said that he was “hurting badly" over the split with Brook, but said that there was no one else involved.

A spokesman for Miss Brook has confirmed the split.
