Check out this first look still of Sasha Pieterse in her new film G.B.F.!

Here’s the film’s synopsis: Social warfare erupts in a suburban high school when the school’s powerful “Clique Queens” (Pieterse, Andrea Bowen, Xosha Roquemore) try to turn Tanner (Michael J. Willett) and Brent (Paul Iacono), 2 closeted gay teenagers, into the must-have social accessory of the year: The Gay Best Friend [“G.B.F.”]. As the girls fight for the edge to make them most popular, the boys deal with dysfunctional parents, down-low jocks and horny Mormons, culminating in a Prom that will blow the top off their town.

Principal photography on the flick, which also stars Will & Grace actress Megan Mullally, wrapped earlier this month and the film is expected to be released in 2013. We can’t wait to check it out!
