Lively, who portrays Serena van der Woodsen in the show, said that she intends to move away from "commercial" roles.
She told Marie Claire: "I'm on a very commercial show, so the last thing I want to do is a commercial movie.
"I wanna take risks, I don't wanna play it safe. I mean, I could probably make more money if I did more commercial projects. It would be nice to buy an apartment but I'm 22 and I don't need to yet.
"I live in New York City. So, I'm able to differentiate between what I want and need and what I want more is to do great roles."
The actress added that she doesn't know how much longer Gossip Girl will be running for: "We have six-year contracts but who knows how long TV shows ever run?
"They don't always go the full season contracted… We're in season four."
