On the October 8 episode of The Tyra Banks Show, she says she and her family were in Turks and Caicos to visit their grandfather who "was dying."
When they arrived at the airport, "Nikki Blonsky ... was very rude to my aunt," Bianca says.
"My aunt had two babies in her arms, and she told my aunt, 'You can leave. You can go away,'" Bianca recalls. "I was really upset by that because my aunt and I are close."
When Bianca spoke up, Nikki turned to her and said, "'You need to mind your business. You don't know what’s going on.' She went off," the model says. "There was a lot of words exchanged. I got really defensive."
Golden's mother, Elaine, then intervened, telling them both to calm down.
That's when Blonsky's father, Carl, approached her, Golden says.
"Before my mom could walk away from us, her father ... punched my mom," Bianca tells Banks. "He knocked her out. He hit my mom with such force she stumbled back, and when she stumbled back, the whole family got up and attacked my mom."
Bianca said Nikki then kicked her mother in the crotch.
"That's when my mom fell ... completely," Bianca says. "Both the families were arguing. It was like a scene out of a movie. Airport security finally came and separated everybody."
All the while, Bianca claims the Blonsky family were spewing racial epithets at them. "Her father and mother started saying, ‘They got rabies, they got rabies!'" says Bianca.
Bianca says her mother confided in her on the way to the hospital.
"She said to me, 'Bianca, if anything happens to me, I need you to take care of your brother and sister,'" Bianca says. "To hear that from your mom... I was freaking out."
After suffering a broken nose, fractured skull and internal bleeding, Bianca says her mother is now in therapy.
Says the model, "She walk now and she’s back."
Nikki and her dad are due in court Dec. 1, where she will answer to charges of common assault and actual bodily harm.
Carl is facing a count of inflicting grievous bodily harm.
