On Wednesday, Brittany Murphy's husband Simon Monjack and the late actress' mother Sharon will talk to CNN's Larry King.

It will be Sharon's first interview since her daughter, 32, died Dec. 20.

Monjack has denied that Brittany had a prescription drug problem or an eating disorder.

An official cause of death is unknown; toxicology results by the L.A. Coroner are due soon.

At her Christmas Eve funeral, Monjack called his wife his "soul mate."

He said that "mystery is the nature of love and you never know when or where it will strike or how quickly it will be taken from you."
