I think Lady Gaga is the real deal. So are Katy Perry and Avril Lavigne. The Pop princess that seems to have lost her way but has an abundance of talent is Cristina Aguilera, she could have been great, and maybe she still can, but she doesn't seem to know what her artistic identity is, burying her talent under self-indulgent vocal runs and vaudeville make-up. Lady Gaga get's away with what many can't. The saying is to carry it, you gotta be it. I don't think her costumes are an act, just self expression on crack.
