Los Angeles, California (CNN) -- The trial of Anna Nicole Smith's boyfriend Howard K. Stern and two doctors for allegedly conspiring to feed her drug addiction nears an end with prosecutors expected to rest their case Thursday.
Jurors watched a video on Wednesday of the Playboy model singing, kissing and bathing with her infant daughter just two months before her February 2007 death.
"Momma didn't mean it, I'm sorry," Smith said when Dannielynn began crying as she washed her face.
Prosecutors showed the 13-minute video to support their argument that Smith's speech was slurred and her mind was groggy from drugs.
The defense does not deny Smith took a lot of drugs, but they contend Drs. Khristine Eroshevich and Sandeep Kapoor were treating her for chronic pain that other doctors had also diagnosed.
"If she's being treated for pain, it's not illegal," Los Angeles Superior Court Judge Robert Perry said last week.
Judge Perry has suggested several times in recent weeks that the prosecution had fallen short in proving the core of its case, including that Smith was a drug addict.
The judge told the lawyers on Monday that he was considering dropping some of the charges before the case goes to the jury.
