BillboardAwards/Janet looked great..where was her voice?

Janet Jackson looked amazing. I even liked her outfit. She was trim and very young looking as well. Her moves were spot on.

Now I understand having to lipsynch. Hell I know there's no way I could sing and move like that but when she did sing her voice sounded horse and bad almost like a man. Funny thing is afterwards she sounded like little girl when she spoke.

Any thoughts on this?
