Best;
Leighton Meester and Ed Westwick (Chuck/Blair) Gossip Girl - Haven't had much sexy time this season, but omg, their sexual tension/chemistry in season 1 was off the charts!
Worst;
Robert Pattinson and Kristen Stewart (Edward/Bella) Twilight - LOLOLOLOLOLOL. Their scenes make me die laughing. So. Awkward.
