ET has the details...

Nikki Blonsky is speaking out on what she calls "absolute lies" surrounding her unexpected arrest in the Turks and Caicos Islands last month.

She first talked to ET, telling our Thea Andrews in her first interview since the incident, "You never expect things like this in your life, but you take life one day at a time, and you deal with situations."

But after former "America's Next Top Model" contestant Bianca Golden told Tyra Banks her version of the events detailing the airport beat down, Nikki is telling her side to People magazine.

Both admit there was an argument that led to violence in the terminal, though Bianca says it was Nikki's father who struck first -- punching her mom in the head.

"Absolute lies," says Nikki.

She says the fight erupted when Bianca's family became angry that some passengers were saving seats in the departure area.

Things escalated when Nikki told Bianca not to point her finger in her face. "That's when she stood up, pulled her arm all the way back and said, 'F@#% you, you white b!*#$.' And she closed her fist and punched me," she says.

Nikki, her father and Bianca all face assault charges related to the brawl.

Now Nikki says that she lives "every day in pain."

"The hardest part for me is to see my parents walk around in severe upset and sadness," she says.
