Blake Lively carried her iPad and a Christian Louboutin bag on the set of Gossip Girl in NYC this morning. She's not the only cast member braving cold temperatures as Penn Badgley is in Sundance showing off his acting skills in Margin Call. Their costar Leighton Meester, meanwhile, was treated to warmer weather in LA recently. She went west to premiere The Roommate on Sunday, when she opened up about her hopes for the small-screen romance between her Blair Waldorf and Ed Westwick's Chuck Bass. The series, one of your current favorites on the CW, made its 2011 return to TV last night, and the episode was full of great OMG moments.
