What do you think of katy perry on american idol?

i though that it was very obnoxious that she wore Adams name on her cape. i understand that it is freedom of speech but it was on american idol witch is a voting show. some girl seeing that katy perry likes adam is going to make her want to vote for adam. i dont have anything agents him it would be the same if it was kris or danny but it jsut angers me hat they would let her do that
