Sam Mendes Denies Cheating Rumors

Director Sam Mendes is under fire for reportedly cheating on his wife, British star Kate Winslet, with another British actress Rebecca Hall (inset).

“Utter nonsense,” Sam‘s rep, Simon Hall, says of the infidelity. “Untrue and ridiculous.”

Yesterday, news broke that Kate and Sam were calling it quits after seven years of marriage and a 6-year-old son, Joe. “Even after splitting, they remain friendly,” a source reveals.
