Simon Monjack may be buried next to wife Brittany Murphy

Late actress Brittany Murphy's widower Simon Monjack, who passed away on Sunday, may be buried next to her.

The 8 Mile star's mother, Sharon, who stayed with the British screenwriter even after the death of her daughter, wants the two to be laid close to each other, sources say.

"Brittany's mom and Simon stayed in the same house together after Brittany passed. I don't think either one could handle moving on yet. Her death was sudden, and coming to grips with it was taking time," Fox News quoted a source as saying.

The insider added, "Her mom was her best friend, and she is still grieving. The insider said Sharon Murphy "may handle Simon's arrangements.

"He did want to be close to Brittany forever and he could be buried near her at Forest Lawn in the Hollywood Hills."

Los Angeles police said Monjack died of "natural causes'. It is believed he suffered a heart attack.
