Britney Spears is "Anna Nicole Smith in real time" according to celebrity psychiatrist DR. Drew Pinsky - who fears she could end up dead like the Playboy playmate. Pinsky - who is treating troubled former American Idol star Jessica Sierra - is convinced Britney needs treatment for more than one condition, and could die if she goes untreated. He tells PageSix.com, "She has, in my opinion, more than one possible diagnosis which could include bipolar disorder, addiction to some substance, and post-partem depression, among others. There isn't just one diagnosis with her." Pinsky recommends Spears seeks "at least one year of inpatient in-depth treatment". He adds, "This is a very treatable young lady whom, if she were to receive sustained medical treatment, would stand a much better chance of success."
