Kelly Brook has ended her four-year relationship with Hollywood heartthrob Billy Zane.

It is believed the British model-turned-actress ended the relationship in March after re-evaluating her life following her father's death last year.

Brook, 28, appeared in public without her engagement ring for the first time at Sunday night's BAFTA TV awards.

A source tells 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 U.S. They remain good friends."

Brook met the Titanic star while filming castaway thriller Three in 2004. She had just split with Lock, Stock And Two Smoking Barrels star Jason Statham.
 
The couple had planned to wed in a romantic ceremony at their 600-year-old farmhouse in Kent, England.

A spokesman for Brook has confirmed the split.
