Jason Alexander, who was married to Spears for a couple of days in 2004, spoke with the Sunday Mirror of London to talk about Britney's drug use for fear that she is going to end up like Anna Nicole.

Alexander, who claims he once had a drug-fueled threesome with Spears and a female dancer, and said that he had trouble keeping up with her drug use.
"We used ecstasy at night to party and cocaine during the day to stay awake," Alexander said. "Then we would take downers like Valium or Vicodin to come down and rest.
"She definitely had a problem with drugs when we were together and that was three years ago."

"I took her into the bathroom and threw her in the shower," Alexander said. "She was unconscious. She tripped and fell. I was trying to hold her up and speak to her. She wasn't moving.
"I remember looking down at her all crumpled in the tub with the water coming down. She looked so white and lifeless. I thought she was dead. I thought, 'This bitch is going to f--king die right here in front of me.'"
