eh.. justin and janet used to do it.. and judging by their dry humping on stage, i'd say it was probably intentional. plus the words he was singing as he did it were "i'll have you naked by the end of this song". but oh well. it's not nearly as gross as madonna and britney making out. that was just sick and wrong.
