Larry Birkhead: Anna Nicole Popped Pills on Daily Basis

Anna Nicole Smith's photographer-boyfriend takes the stand in the criminal case against her lawyer and doctors

Today's star attraction in the Anna Nicole Smith drug-plying case/circus: none other than her baby-daddy Larry Birkhead.

Unlike the graphic testimony given earlier this week, Birkhead kept the revelations to the minimum, dropping the nonbombshell that Smith popped narcotics like candy when the two lived together in 2004-06. He said she would ingest medications like methadone, klonopin, Topamax and Xanax on a daily basis.

Birkhead, who has been raising their daugther, Dannielynn, also revealed that Smith never left home without a duffel of drugs, many prescribed to her by one of the defendants, Dr. Sandeep Kapoor.

Kapoor, fellow physician Dr. Khristine Eroshevich and former Smith sidekick Howard K. Stern are facing nearly two dozen felony counts related to Smith's drug intake. All three have pleaded not guilty.

Meanwhile, prosecutors tried to pull out what they claim is a smoking gun...

They have petitioned the judge to allow them to show in court a video capturing of Kapoor kissing Smith at a nightclub and talking about her prescriptions.

A ruling on that matter could come later today. If the request is granted, such footage suggesting she and Kapoor had an inappropriate sexual liason could do significant damage to the defense as it could lend strong credence to the view that Kapoor (who says he is an out homosexual) abused his position and helped fuel Smith's addiction.

Yesterday, government lawyers insinuated that Smith also had a lesbian fling with Eroshevich, but the judge nixed that line of questioning.
