'Jackass' star Steve-O is doing "really good", according to his co-star Chris Pontius.

Steve-O was admitted to a psychiatric ward at Los Angeles' Cedars-Sinai Medical Center last week over fears he was suicidal, and Chris believes it was only a matter of time before his close friend had to seek help for his mental wellbeing.

He told BANG Showbiz: "I haven't spoken to him but he is doing really good. He is doing great. I think to be on 'Jackass' everybody has got to be kind of crazy and we all hang out together and we don't really think about it."

"It didn't come as a shock, no. Everybody's sanity on 'Jackass' is like a progressive illness. Everybody is getting crazier and crazier."

The daredevil, real name Stephen Glover, was charged with cocaine possession just a week before being hospitalized, after police were called to his house to deal with a complaint he was vandalizing his neighbor's property.

Chris, 33, believes Steve-O's drug use is symptomatic of a deep-rooted psychological problem.

He added: "I think when people are abusing drugs it is probably a symptom of a bigger problem that they need to address. And that is what Steve-O is doing at the moment, getting to the root of it."

Chris explained the 'Jackass' crew are planning a big welcome home party when Steve leaves the facility.

The star - who is currently promoting new DVD 'Jackass 2.5 Uncut' - said: "Nothing is ever going to be sedate and quiet with us."
