Last night in Los Angeles, 30-year-old goddess Kaley Cuoco helped celebrate the 200th episode of CBS’s The Big Bang Theory . She showed up in a gown that’s arguably hotter than the one she wore to the Grammys last week . Never change, Queen Cuoco. Congrats on 200 episodes. In semi-related news, this guy still hates Big Bang Theory more than any other human being on the planet.
