Blake Lively Lives The Socialite Life

The star of Gossip Girl may not be an Upper West Side private school girl in real life, but she certainly knows how to live like one. Blonde and bubbly, Blake Lively was radiant in a Chanel mini-dress at the classic fashion label’s Tribeca Film Festival dinner.

She gushed about her passion for fashion on the red carpet before the event, saying, “I own way too much. People have to intervene in my life — my business manager, my publicist and my friends tell me I have to stop going to Chanel.”

Speaking of interventions, the pictures of Mary-Kate Olsen make her look like she’s on death’s door. Yikes. Her corpse make-up isn’t doing her any favors and is that a pouch on the front of her spangly mini-skirt? There is no excuse for that–she is not a Marsupial. She looks like a Robert Palmer music video ho crack baby. To get the full effect, check out the full body shot of her after the jump.
