I don't get it, did Kelly say something about Gaga aside from whatever she was wearing? I don't believe she deserves this unwarranted criticism from fans if she didn't say something that wasn't justified. The show is called 'Fashion Police' (?) which makes it appropriate to either cheer or jeer an outfit, from my perspective at least.
Now I do remember Ciara being a guest on that show and going on a small tangent about Rihanna, so I know the show can get messy at times, I'm just not sure what Kelly said.
