"Hairspray" star Nikki Blonsky is joining David Hasselhoff's daughter Hayley, James Eckhouse's son Zander and Andrew Caldwell in forthcoming ABC Family series "Huge."

The series, a mix of "Ugly Betty" and "Glee," is focused in six teens and staffers at a "fat camp," Wellness Canyon, says Hollywood Reporter. The 10-episode, direct-to-series show is penned by "My So-Called Life" creator Winnie Holzman and her daughter Savannah Dooley, continuing the offspring theme. It's based on a book by Sasha Paley.

Blonsky plays the daughter of rich parents who own a chain of fitness centers; naturally, she's the opinionated comic lead.

Hayley plays Amber, one of the skinniest, prettiest  -- and curvy -- girls at the weight loss center while Zander, an assistant fitness counselor, starts falling for her. Caldwell leads a pack of the popular, thinner teens at the camp.

"Huge" starts airing in late June.
