But, we don't know that LL has been slutty

I mean she goes out all night and parties, but she is never really linked with multiple guys and there is no sex tape -- at least yet. I certainly have gone out until all hours of the morning and not gone home with anyone. Of course, when I was like 20, of course I sewed my wild oats - who didn't?
As for judging her talent, you can judge what you like, but that does not make her talented in the eyes of most.
