Even though they were a celebrity couple that flew under the radar, for the most part, they just couldn't make it. Brokeback Mountain co-stars, Heath Ledger and Michelle Williams have split, Us Weekly reports. A source close to the couple tells the mag that Heath and Michelle, who met on the set of their flick in 2004, "quietly and amicably split a few weeks ago."
The reason? "The relationship had been rocky recently. They tried very hard to make it work but finally decided to separate. They just grew apart."
The couple have one child, Matilda, almost two. "They have a beautiful daughter and they are both committed to being great parents," said the source.
Reps for the couple could not be reached.
