Actress Bai Ling had a potentially dangerous crisis on Sunday’s episode of ‘Celebrity Rehab With Dr. Drew,’ refusing to take her medication, then climbing to the roof of the Pasadena Recovery Center as a way to avoid the staff.

The rehab center’s staff seemed unsure of Ling’s intentions, and they followed her as she traversed the roof. Dr. Drew Pinsky, in particular, seemed worried that Ling might jump.

The troubled actress reportedly suffers from emotional issues and alcohol dependence stemming from sexual abuse by Chinese army officers.
