Michelle Trachtenberg: "I'm Not Like Georgina"

Okay, so she may only be 22 (give her metabolism a few more years), but Gossip Girl's Michelle Trachtenberg says she doesn't diet. In fact, she doesn't even work out.

"I love food, I hate working out," the actress admitted to OK! at the Grammercy Park Hotel, where she helped kick off the longest day of the year with long-lasting Stride gum. "I don't get any of that endorphins and stuff that keeps people going. I went through a chicken fingers phase about a year ago...Chicken fingers, ranch dressing, MMM."

When she does thow in a healthy meal, the actress says she usually eats sushi or a salad and tries to "take a multi-vitamin". And then there's her favorite: "I love club sandwiches; The multi-layer, the cheddar cheese, and avocado."

One thing's clear: Michelle's definitely worked up an appetite playing Gossip Girl's resident mean girl Georgina Sparks. Her character spends most of her time tormenting others around her. But in real life, Trachtenberg says she's nothing like Georgina.

"Unfortunately I didn't have the best school experience because kids can be very cruel," she tells OK!. "I've been acting all my life. Everyone made fun of me."

She continues, "When I was in Elementary School, a girl pushed me down a flight of stairs. I had just finished Harriet the Spy. I was like 10. A year and a half ago I was at a restaurant and all of a sudden I hear, 'Oh my god, Michelle! It's Sandy!' She's telling all her friends we used to be best friends in school. It took me a second to realize who it was. Then I was like, 'I haven't seen you since you threw me down a flight of stairs. Hope you have a great day.'"

The cast of Gossip Girl has been hard at work shooting next season (which premieres Sept. 1). As for what Georgina will be up to in coming episodes, Michelle says she hopes to see a lot more evil unfold.

"I've never really understood those actors that don't want to play villains because I think that if you do a bad ass job playing the villain and people leave the theater or turn off the TV, you're getting emotion from them, so that's cool."

She adds, "It has been the most fun I've ever had playing a character," she says. "Now I walk down the street and I either get 'Oh you b**ch' or 'Oh my god I f***ing love you' and I'm like 'hmm, ok!' 'Thank you?'

Michelle admits she only gets nervy when she has to do a love scene--especially when it calls for kissing your co-star's real life boyfriend! She recently had to make out with Penn Badgley, who is dating Blake Lively.

"It's always a little weird kissing a co-star because I think kissing is one of the most intimate things in a relationship," she says. "But I think Blake and Penn make a great couple."

And as for rumors that she doesn't get along with the rest of the female cast?

"It literally couldn't be further from the truth!" she tells OK!. "Leighton Meester and I are on bbm blackberry messenger, Blake and I text...And the boys are hot!"
