Our favorite Upper East Side Princess, Leighton Meester, is the covergirl for the June issue of Cosmopolitan.  Inside the magazine, Leighton spills on her role as Blair Waldorf and her boyfriend, Sebastian Stan (who plays Carter Baizen on Gossip Girl).

• On playing Blair Waldorf: “The evil side of Blair is somewhere in me.  Acting her out is like therapy.  I get to do things nobody would every say or do in real life.”
• On guys: “I’m not into bad boys. I think the term is stupid. A guy who cheats on you or is not nice to you? What is that? Nowadays, I’m much more mature in relationships. I’ve let go of the bullshit. I think more about the deal makers than the deal breakers. I want a guy I can look up to.”
• On Sebastian Stan: “I’ve never fallen in love right off the bat. I get scared to say, ‘I love you’ too soon because it means so much. It means you’re not seeing an end to things.”
• On Blair’s romance with Chuck Bass: “They’re so perfect because they get each other. Chuck knows about her deep, dark side and he finds it hot. But the best part of their relationship is that it’s realistic. People don’t always date for a while and then slowly fall in love. They start by hooking up one night. It takes time to get to know someone, and then you realize that you’re in love later on.”
