'Jackass' star Steve-O has been admitted to a mental health unit.

The 33-year-old prankster has reportedly been under observation at Los
Angeles' Cedars-Sinai Medical Center since entering the hospital on Sunday
(03.09.08), amid fears he is suicidal.

Steve-O - who was charged with cocaine possession last week - is staying in
the Thalians Mental Health Center, the same unit where Hollywood actor Owen
Wilson was treated following his suicide attempt last year.

A source said: "Steve-O is in hospital now, not for injury but for
observation. He'll probably be there for another two weeks."

Friends became concerned for his wellbeing after Steve-O sent a series of
emails containing references to death and suicide.

He reportedly wrote to friends: "I betcha I break more than nine bones if
nobody comes with something to catch me, because, mark my words, I will
fall!"

In a separate email he then wrote repeatedly: "I'm ready to f***ing die."

A source said: "These last emails definitely had something to do with it but
he's been headed towards this for a few months."

Steve-O - real name Stephen Glover - was arrested earlier this month after a
neighbor contacted police complaining he was vandalising both his own and
his neighbor's apartment.

Police found a small quantity of drugs on him when he was arrested.

Steve-O was evicted from his loft apartment after the incident.

He has previously admitted he might need psychiatric help, saying: "My
family is convinced that I've got bipolar disorder. I don't know if I agree,
but I've come to terms with the fact that I'm somewhat f***ed in the head. I
agreed to go to a psychiatrist for a professional evaluation, to try and
figure out what specific category of nutjob I fall into."

The drugs just make him worse. Is he sooo bored with his life?
