Kelly Brook and Billy ZaneThe end may be nigh for Billy Zane and Kelly Brook’s relationship.

The former glamour model met Titanic star Billy two years ago when they filmed the movie Three together and the couple were rumoured to be planning to marry later this year.

A source revealed: “Kelly and Billy have been having lots of rows.”

“They are still together but things haven’t been great. They’ve enjoyed a long honeymoon period since they first met and fell in love but this is the first period in their relationship when there have been problems.”

“All their friends are hoping they can sort things out because they are such a great couple.”
