Alex Frnka is pretty in peach at Seventeen Magazine’s September Issue Celebration held at the W Hotel Westwood on Thursday night (August 2) in Westwood, Calif.

The up and coming starlet wore a Gloss Army dress with a Lauren Merkin clutch and Renee Sheppard jewels.

Alex‘s new MTV show, The InBetweeners, is premiering on Monday, August 20th @ 10:30PM ET/PT.

The show takes a comedic look at a group of teenagers navigating high school and charging into adulthood the way everyone does…by taking one step forward and three steps back. Whether humiliating themselves in an effort to impress the girl of their dreams, or mercilessly mocking their friend for driving a bright yellow clunker with a cassette player and one blue door, get ready to embrace the “inbetween.”
