I've never heard of this before. Doesn't seem that special. I think my opinion is objective because I don't have that " I have to praise it b/c it's a classic!!1" bias!
I don't think Gaga is fat necessarily. I just think she's just one of those people who easily have a double chin when they aren't thin, if you know what I mean. My cousin has a double chin as well but he's not really that fat. Anyhow, she can always photoshop her fat away. The crappy music needs to go though.
