Kelly Brook split from fiancé Billy Zane this week. The Sun reported that after four years Kelly decided the Titanic star wasn't her cup of tea. "After much soul-searching, Kelly decided Billy is not the man she wants to marry and 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," an insider said. "Billy was keen, but she kept delaying plans for the big day. He started asking questions - and they eventually decided to go their separate ways."
