Nicole "Nikki" Blonsky (born November 9, 1988) is an American actress and singer. She is best known for her role as Tracy Turnblad in Hairspray, a 2007 screen adaptation of the stage musical adaptation of the John Waters film of the same name and as Maggie Baker in Queen Sized.
Blonsky was born in Great Neck, New York, which is in Nassau County on Long Island NY, the daughter of Karen (née Smeja), a school aide, and Carl Blonsky, a municipal worker for the village water pollution control district. Blonsky worked at Cold Stone Creamery before starting her work on Hairspray.
She graduated from Great Neck Village School in June 2005, having transferred into the school from Great Neck North High School in her sophomore year, because she was teased for being overweight, but in the High School she transfered to, she became very popular. Her father is Jewish but she was raised in her mother's Catholic religion. She wanted to be Tracy Turnblad when she saw Hairspray on Broadway. She tried out for the part then, but was told she was too young. Coincidentally, she was born the same year the original Hairspray film was released.
