Those poor singers here include Selena Gomez_Christina Aguilera_Jessica Simpson_Ashlee Simpson_Emily Osment I personally love christina aguilera and ashlee simpson,as well as i like emily osment. i think christina aguilera didnt sound all the way bad,just few notes in some performances,therefore,she is just a candidate here for the public. Of ashlee simpson,she is my all time favourite singer.but i have to be honest,she couldnt sing piece of me,she never sings it well.And her voice is too nasal
