i really dont know what chould be kellys best note she has really hit some nw is diffentally up there my i remember my mouth dropping when she did that note. and then theres the low performance on the teen choice awards that is a memerable one and the anymore part on bthe is diffentally one up there. i also rember doing the christmas show last year with fantasia she did an amazing high note there. i do agree with that one dude that was talking about amlt this on the breakay tour is one to remember lol they r just so many to choose from
