I think GaGa has changed. In "Just Dance" she seemed like an extremely likeable weird celebrity. But in "Poker Face," she was WAY to out there, and that has stuck with her since then.
i like her music and I used to like her but she seems very fake. Her whole personality seems like an act in order to stay original and gain exposure. These old videos show that she used to be normal. Now that she's famous, she's created this cocky imagine that is getting really annoying
