There is something that doesn't sit right with me.
Singers does not equate being a fashion model, film star, spokesperson etc. They sing and should be judged, primarily, by their voice. I'm glad Gaga isn't considered "sexy" by the majority of the public. It relieves some of the pressure that has been aggravated over the past 15 years or so to always look sexy.
If anything I admire her for that alone. She's not here to give us wet-dreams. She's here to sing some silly, catchy songs for our entertainment.
Plus I think it's good that she tries. While she doesn't always get it right she would never admit that and I like that. She's honest and is not afraid to be full of herself -- a nice break from all these "modest" stars. I like that she throws a few 4 syllable words and the like around too. She knows what she is about. Plus she's only 25 and already one of the biggest stars on the planet (achieved publicly in just 3/4 years). Let her make a few mistakes.
