Nikki Blonsky says she lives "every day in pain" since the July 30 fight involving the family of Bianca Golden, a former contestant on America's Next Top Model.
Speaking for the first time about the brawl, the Hairspray actress, 19, tells PEOPLE that she and her father Carl are "completely destroyed" by the incident.
"The hardest part for me is to see my parents walk around in severe upset and sadness," she says.
The fight erupted at the Providenciales International Airport, where the Blonsky family was waiting to fly home from a Caribbean vacation in the Turks and Caicos. Blonsky says that the Golden family – including Bianca, her mother Elaine and her brother George – grew angry when some passengers were saving seats in the departure area.
