I honestly don't see what the big deal is. Yeah her VMA performance was a bit crazy and ridiculous, but we've seen the same kind of thing from Lady Gaga, Pink and others in the past and no one ever thought twice about it.
And yeah she says some stupid and idiotic things at times, but she's a 20 year old pop star
. It's kind of their job
to get attention by acting ridiculous and saying stupid things.
I certainly have a lot more respect for her than I ever did for Britney Spears. Mainly because she can actually sing. I have her latest album on my phone and it's pretty damn good.
