Steve-O is on suicide watch. The Jackass daredevil has been hospitalized for attempted suicide, it has been claimed.

While EW has released its list of smart people in Hollywood, New York Daily News has published its own list of "50 Dumbest People In Hollywood" and Lindsay Lohan is on top.

The list cites Lohan for "poor movie choices, delinquent behavior and bad taste in men," the NY Daily News says. She shares the spotlight with other celebrities lower in rank: Kim Kardashian, Spencer Pratt, Jessica Simpson, Keifer Sutherland, and Coutney Love just to name a few. Below is the complete list of the unflattering inventory.

Jackass star Steve-O claims Lindsay Lohan once stole a bag of cocaine from him.
