Simon Monjack has fervently denied rumors that after the death of his young wife, Brittany Murphy, he not only shares a home with her mom Sharon, but he's sharing a bed as well!

Monjack recently told Access Hollywood, "We don't have sex, number one. Number two, she is a woman that has toxic neuropathy, which means she can barely walk." And thirdly, "I live downstairs, she lives upstairs."

Ok, we really want to believe that Monjack is telling the truth, because the alternative would be too creepy, but why would a woman with "toxic neuropathy" who can "barely walk" live on the top floor of a house? Wouldn't she want to be on the first floor so she doesn't have to deal with steps? Also, his denial is that they "don't have sex." Not that they're not involved. Was that just the way he phrased it or is he covering up for something?

Hmmm...
