In surprising couples news, actors Michelle Williams and Heath Ledger have called it quits after three years together.  (Those betting on Katie Holmes and Tom Cruise to be the first major post-Dawson’s breakup better pay up).  The Oscar-nominated actors met on the set of Brokeback Mountain back in 2004.  The couple, often rumored to be secretly married, have a young daughter together. 

Ledger is currently filming The Dark Knight—the highly-anticipated sequel to Batman Begins—in which he will star as ‘The Joker’.
