Sasha Pieterse was a pretty little stunner at the Hollywood premiere of her latest flick, G.B.F., on November 19.

The Pretty Little Liars star made us green with envy in a sexy — and shiny! — emerald Mikael D dress, nude Jimmy Choo pumps, a black and gold Vince Camuto clutch, and stunning Gaydamak jewels. Sasha rocked a classic side-swept ‘do — seriously, look at those curls! Years of being on the run has a done a girl good, right PLL fans?

In G.B.F., Sasha stars as high school Queen Bee named Fawcett. Not only does she have major attitude (Ali DiLaurentis 2.0, anyone?), but she’s also in the running for Prom Queen. What’s going to help Fawcett win the crown? A gay best friend, of course! The quirky film centers on the three most popular girls in school — Fawcett (Sasha), Caprice (Xosha Roquemore), and ‘Shley (Andrea Bowen) — as they compete for Prom Queen and for the affection of Tanner (Michael J. Willett), the school's recently outed outcast, who they think will help them be fabulous. Think of it as Mean Girls meets Clueless.

If it doesn’t already sound like your new favorite film, just look at this cast! Sasha stars alongside Awkward.’s Molly Tarlov, funny lady Megan Mullally, and Natasha Lyonne. In other words, it's perfect.

G.B.F. premiered on April 19 at the 2013 Tribeca Film Festival in New York City. Watch the trailer here, check out Sasha's stunning red carpet look below, and tell us what you think!
