She did Love The Way You Lie II by herself and then Eminem came In and did his part and segue waged into his performance with Dr. Dre. She WAS suppose to OPEN the show by herself in 2009 (she said it was suppose to be the performance of her career) and it never happened.. for obvious reasons.
I am pretty sure Chris was performing with her that night and you know she would never be able to top that epic WMN performance she did.
EDIT: And they would never let her perform Talk That Talk... you guys.
