Brittany Murphy’s Husband Denies Sleeping With Mother-In-Law

Brittany Murphy’s widower is furious over allegations that he is sleeping with his dead wife’s mother.

Simon Monjack — a slick British-born producer who wed the tragic star in 2006 — insists detractors concocted a rumor that he is sleeping with his mother-in-law, Sharon Murphy, because he’s been sharing a house with the woman since the actress died last winter.

Monjack told The Sun Monday: “We don’t have sex, number one. Number two, she is a woman that has toxic neuropathy, which means she can barely walk. I live downstairs, she lives upstairs.”

The Clueless actress collapsed and died after a battle with pneumonia last December. Monjack told the paper that he and Sharon are considering moving to New York City to escape the pain of Brittany’s death….Of course, they’ll renting separate apartments.
