Well I think she did great, even beyonce couldn't hit whitney's high notes! So it really no argument who could do better! Even Jennifer Hudson couldn't Whitney high note and Jennifer has a stronger voice then beyonce and kelly! So you tell who could hit them notes! I will tell u what I think! So het off of Kelly! She has great career! Like Kelly said in her song,"keep on talk cause I love the attention, ... And if you want to see me go high in the sky b/c this chick is so fly! I'm that chick!"
