Billy Zane, Kelly Brook Headed For Splitsville?

Hollywood couple Kelly Brook and Billy Zane's engagement is reportedly on the rocks after a series of spats. The pair are expected to marry this year, but friends fear their three-year relationship could be over. A pal tells The Sun, "Kelly and Billy have been having a lot 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.
