Actor Billy Bob Thornton has ended his romance with his latest girlfriend - even though he'd planned to marry her.

The eccentric MONSTER'S BALL star, who already has five marriages under his belt, split with Tomb Raider beauty Angelina Jolie last summer (02) after a two-year union, before he started dating stunning model DANIELLE DOTZENROD.

And just last month (MAR03), sources told American magazine US WEEKLY he planned to walk his girlfriend down the aisle, with FRED CUELLER of DIAMOND CUTTERS INTERNATIONAL confirming the actor had purchased a three-carat-plus blue diamond ring.

But a representative for the 47-year-old says the actor is now done with Dotzenrod.

Thornton, whose divorce from Jolie has yet to be finalised, is currently busy making the movie The Alamo in Austin, Texas.
