It's only been one day since the death of actress Brittany Murphy, and already her husband Simon Monjack is talking to Access Hollywood...

"My world was destroyed yesterday," he says, adding: "I loved what Ashton wrote on Twitter. It was comforting to me. I couldn't have said it better."

Simon reveals that his wife "had laryngitis" and "had been tired at the end of the year" after making a couple movies. Nonetheless, he says Sunday started off as just "a regular day."

Brittany was found unresponsive in the shower - her mom Sharon "went into the bathroom because she had been in there a long time," says Simon. "Her mom screamed for me and I ran. Then called 911."

So sad. We wish Murphy's husband and family all the best during this difficult time.
