This situation was even worse than we thought.

Demi Lovato was in such dire straights when she overdosed last week, her assistant thought she was dead when she discovered her lying in bed unconscious, TMZ reports.

The assistant was screaming "She's dead, she's dead" when the bodyguard arrived, and his quick thinking is what saved the singer's life. There was blood and vomit on the "Skyscraper" songstress' pillow, and she wasn't breathing, which prompted the bodyguard to prop her up to clear her airways and administer CPR before the ambulance got there.

The chart topper is due to be released from the hospital any day now, and she's agreed to go to rehab. Arrangements have already been made at a facility, and there will be no lag time. She will go straight from Cedars-Sinai to the treatment center, and is expected to stay for at least 30 days.

If this isn't a wake-up call, we don't know what is!
