She's only singing over parts of the track, this song has a lot of stuff that she can't do at the same time... it would be like doing three voices at the same time XD... It's a good performance, not her best but she managed to go through it... She's doing it better at the D2K Tour...
She's fabulous. I'm agree that it's not her best performance. But she's singing live most of the song here unlike D2K Tour. Her outfit is amazing. But wtf with her hair? She always has the worst wigs.
The d2k tour was awesome and she was live you could hear she was live cause she made some mistakes in the Dallas show so sit down u don't know what ur talking about bye
