"Hairspray" star Nikki Blonsky and "Top Model" vixen Bianca Golden are clear of assault charges stemming from their summer bust-up in the Turks & Caicos.

The pair -- along with several family members -- were pinched for getting into a vicious slapfight over a seat at Providenciales International Airport. Bianca's mom was injured in the fracas.

Nikki's dad, Carl, meanwhile, still faces assault charges in the case, and could spend up to five years in jail if convicted.
