Mendes denies cheating on Winslet

The couple announced their split on Monday (15Mar10), revealing their seven-year marriage came to an end earlier this year (10).

Speculation has been rife over the reason for the break-up, and recent reports alleged Winslet ended the union after her husband grew close to Hall, who was cast in two of his plays.

But a spokesman for Mendes is adamant the reports are completely unfounded.

The rep tells E! Online, “Utter nonsense. Untrue and ridiculous.”

He also tells the New York Daily News, “There is absolutely no truth to this. Sam and Rebecca are professional colleagues. That’s it.”
