Haley Ramm pins back her short red hair with a beautiful hair piece as she attends the 2010 Teen Vogue Young Hollywood Party held at Paramount Studios in Los Angeles on Friday night (October 1).

The 18-year-old actress was just cast in MTV’s upcoming WORST. PROM. EVER. Haley tweeted earlier today, “Just spoke to the wardrobe stylist for Worst. Prom. Ever. I’m gonna love this character! Fun stuff! :)”

JJJ‘s done some digging about the characters and we’re guessing that Haley will be playing either Heather or Nev:

Heather is a high school senior, conservatively beautiful and preppy. She’s the overachieving high school valedictorian, class president, and resident good girl who impulsively asks bad boy Colin to prom after he dares her to do something crazy for once.

Neve is also a high school senior; a fun, slightly ditzy hottie with a killer body but she’s been burned by love in the past and wanted to make sure that her jock boyfriend, Justin, was with her for the right reasons, so she’s held off on having sex with him. However, on prom night, she feels right about sleeping with Justin and prepares for a romantic evening.

WHICH CHARACTER do you think Haley will play?
