I’ve never really understood those couples who constantly break up and get back together. After all, if a relationship ends, it’s for a good reason, right? Well, Kelly Brook and Billy Zane must enjoy the drama, because they’ve split “for good” one more time:

It’s claimed the sexy brunette ended her four-year romance with US actor Billy in a tearful phone call last week. The news comes just three months after Kelly last ditched fiancé Billy, leaving the Titanic star devastated.

They quickly reunited when busty Kelly realised they were happiest when together. But it seems she’s changed her mind again – and has brought the curtain down on their relationship once more.

The couple wanted to give it one more shot, but it soon became evident the spark was no longer there.

Poor Billy Zane. While Kelly Brook doesn’t seem so bright, this may account for her disturbing pattern of behavior. However, in Billy’s case, you can’t really blame him for hittin’ that. For the evidence, just check out these Kelly Brook bikini piccies:
