Every time a celebrity couple announces their split, rumors of infidelity start to spread like wildfire.
Earlier this week Kate Winslet announced that she and her director hubby of six years are separating, and everyone assumed it was because one of them has already moved on.
There were reports that Kate was furious with Sam for becoming so close to British actress Rebecca Hall, but his reps claim the story is "ridiculous, utter nonsense" and "untrue."
He also tells the New York Daily News, "There is absolutely no truth to this. Sam and Rebecca are professional colleagues. That's it."
Of course it's only a matter of days before stories about Kate being in love with Leonardo DiCaprio start to make the rounds on the internet.
In the case of Kate and Sam, it seems they simply fell out of love and decided to move on.
