Anna Nicole Smith has lashed out at her mother for making TV claims that the former model's partner, attorney Howard K Stern, was to blame for her son's death.
Virgie Arthur appeared on several US TV news shows after the death of 20-year-old Daniel Smith in September, offering her love and support to her estranged daughter, but insisting something was wrong about the death of her grandson.
Arthur went so far as to suggest Stern was responsible for the tragedy.
Now, Anna Nicole is taking aim at her estranged mum with an angry attack on US TV news show Entertainment Tonight.
Filmed recently at Smith's home in the Bahamas, the blonde speaks through clenched teeth and fights angry tears as she fumes: "How dare you, how dare you… I see her on CNN telling everybody that I killed my son or Howard killed my son.
"She kept trying to say that I had all these drugs; I had to give them to him because he didn't do drugs and he didn't do this and he didn't do that. How does she know? She didn't know my son."
In the tense interview, Stern admits he set up a phone chat between his girlfriend and her mother days after Daniel died on September 10.
He recalls, "Anna was hysterical… She left a message. It was a couple of days after that (when) her mom ended up on the media talking about the message."
Angry Smith adds: "She hasn't seen my son since he was probably about five years old. She doesn't know him, she doesn't know me. For her to go out there and make these ridiculous statements about me killing my son or Howard killing my son, who does she think she is?"
And she ended the interview with a chilling message: "When I saw her on CNN and I saw how evil she was and how evil she looked… bring it on, Mom, Mommie Dearest, bring it on."
