Nikki Blonsky is facing litigation from a pair of former managers who are demanding a share of the royalties from her role as Tracy Turnblad in last summer’s smash box office musical Hairspray.

In documents filed in New York Supreme Court on Monday, Margaret Karaszek and Michael Ostrowski, partners in the Morgit Management that once represented Nikki, accuse the twenty year old actress and her mother Karen of breaching their contract by not awarding the company twenty percent of her earnings in the 2007 film, which co-starred Zac Efron, Queen Latifah, Amanda Bynes, Brittany Snow, and John Travolta.
