katerebeccaFINAL.jpgKate Winslet and director Sam Mendes are no longer a happily married couple, and according to the UK's Daily Mail, the 34-year-old actress is blaming her split on 27-year-old actress Rebecca Hall.

Reports claim that Hall and Mendes grew close over the years while working together on theatre projects in New York and London. The two first met back in 2006, when she made her film debut in Starter For 10 in which Mendes was executive producer.

Friends of the actress also say Hall, who has been described as "totally Sam's type," gave Mendes a "shoulder to cry on" during rough times in his 6-year marriage to Winslet.

However, a source close to Mendes tells X17online: "Sam and Rebecca are friends. They are not involved in any kind of a ‘relationship’ and that any suggestion otherwise would be very wide of the mark.

A source close to Hall adds, "Yes, they know each other. Anything beyond that is just crap.
