From Harriet the Spy to Dawn on Buffy the Vampire Slayer, actress Michelle Trachtenberg has had her share of fun roles, but she tells OK! that her brief stint playing Georgina Sparks on Gossip Girl has been the most enjoyable yet.

“She's an evil vixen,” the brunette beauty told OK! at the 10th anniversary for Gen Art’s Styles’ competition at Sunglass Hut. “I’ve had more fun playing Georgina than any other character I’ve done.”

However, a lot of Michelle's friends are having trouble divorcing the character she's played on TV from the sweet 22-year-old she is in reality. “I get a lot of text messages on Tuesday morning, like ‘Oh you bitch, you’re evil, we hate you,’" she explained. "So I guess I’m doing a good job!"

And even though she didn't join the cast until the last handful of episodes this season, Michelle had no problem getting along with the close-knit cast. “They were all really welcoming and everyone was so accepting saying, ‘We are so excited you are here, we heard you were coming.'"

In fact, the first co-star to welcome Michelle was Blake Lively. “A lot of my scenes are with her, so she was the one that I talked to most, and we spent the most time together,” the native New Yorker explains. “But we all hang out on the weekends as well, so that’s nice.”

Without admitting that new pal Blake is actually in a romantic relationship with co-star Penn Badgley, Michelle coyly admitted it was a bit strange smooching Penn in front of his rumored girlfriend, saying, “It’s always weird kissing a co-star that you aren’t in a relationship with.”

So will Michelle be returning next season? “I really don’t know. I honestly think that is up to the powers that be,” she shrugged. “I’ve had an amazing time with Georgina so it would be super fun — and you’re not dead until you’re dead!”
