American actress and singer, Nikki Blonsky, has an estimated net worth of $625 thousand. Nikki Blonsky was still serving scoops at Cold Stone Creamery when she received the news that changed her life forever. An aspiring actress who was once deemed too young to portray dancing Baltimore teen Tracy Turnblad in the Broadway production of Hairspray, the then-17-year-old New York Village High School student thought her shot at stardom had slipped away by the time a film version of the hit musical was announced. Instead, a keen-eyed New Line assistant brought Blonsky's audition tape to the attention of producers in charge of the feature adaptation, and the rest, as they say, was history. A camera hit the road to capture footage of the finalists for the film role, and director Adam Shankman appeared at Cold Stone to tell Blonsky she'd landed her dream role. Though Blonsky had previously appeared in Great Neck productions of Hair and Alice in Wonderland, she was a virtual unknown at the time she was cast in the role originated by actress Ricki Lake back in 1988. Born Nicole Margaret Blonsky on November 9, 1988 in Great Neck, New York, United States.

She is best known for her role as Tracy Turnblad in the 2007 film Hairspray and as Maggie Baker in the 2008 television movie Queen Sized. She is also known for her main role in the ABC Family original series Huge.
