She’s baaaaaaack!

Michelle Trachtenberg returns to Gossip Girl on Monday night to stir up some more trouble on the Upper East Side as the deliciously evil Georgina Sparks.

The actress admits she loves playing the bad girl.

“The nasty b!tch is back in town,” Trachtenberg told People in a recent interview. “It’s super fun to play the bad girl. I love bringing out the inner nasty.”

For the 23-year-old Michelle, pulling out her claws and unleashing a fierce, wicked side is a “challenge,” but she says she has a pinch of evil buried in her.

“Every woman secretly has an inner b!tch deep down inside - including myself,” the actress said. “But with the scenarios that Georgina is in and the lines from the script, the evil naturally comes out and flows really well for me.”

But don’t expect her onscreen persona to rub off on her in real life.

“I don’t take the nastiness off set, but sometimes when paparazzi get in my face, Georgina comes out,” says Michelle, who can also be seen with Zac Efron in 17 Again.

While Trachtenberg was absent from the set for most of this season (Georgina is currently serving time at a reform school after her shenanigans on the first season), some of her Gossip Girl co-stars have fallen for each other.

Is there some kind of love potion circulating in NYC?

“I haven’t tasted or drank the Gossip Girl love potion yet because I’m actually not dating anyone from the set,” Trachtenberg jokingly said. “But we all roll up with Red Bull in the morning, so maybe there is something in there.”

With Ed Westwick dating Jessica Szohr, Leighton Meester meeting boyfriend / guest star Sebastian Stan on the set, and Blake Lively and Penn Badgley still going strong, Trachtenberg admits it’s only a matter of time before costars to hook up.

“There’s bound to be love on and off camera because actors work closely on set together pulling 16 hours a day with each other,” Trachtenberg said.

“You spend such close time with each other and everyone is really pretty and very attractive. People just tend to gravitate towards each other.”

When it comes to finding her own ideal man, the awesome actress says she likes a mix of a Chuck Bass bad boy and a sensitive, romantic Dan Humphrey.

“Every girl likes a bad boy, but he has to have a sensitive side - that makes a fantastic man,” she said. “But I like older men, and [Ed and Penn] are like family to me. I couldn’t think of a seven minutes in heaven scenario with them.”
