Anna Nicole Smith Doctor Under Investigation  4/7/07

Anna Nicole Smith's psychiatrist is at the centre of a new California Medical Board investigation after prescribing all 11 drugs the tragic model was taking when she died in February (07).

Dr Khristine Eroshevich was Anna Nicole's personal medical consultant up to the star's death in a Florida hotel suite - and she even accompanied Smith to the Seminole Hard Rock Hotel & Casino for part of what was to be her last vacation.

Eroshevich has been a regular on US TV news shows following the tragedy, talking about her relationship with Smith, but now it's medical officials asking the questions after it came to light earlier this week (beg02APR07) that all 11 drugs found in the hotel room where Anna died were prescribed by her.

This is the second doctor under investigation for prescribing practices involving Anna - CMA officials are also investigating DR Sandeep Kapoor, who prescribed methadone to Smith under an alias when she was eight months pregnant, according to TMZ.
