She got nervous performing it, that happens to even the best artists in the business. People forget things that they know like the back of their hands all the time, because their nerves tend to get the best of them.
How come she got the lyrics wrong the first time sis?
Inexcusable.
Calm yourself... Lol. This WAS the first time. This was the rehearsal/sound check BEFORE the live performance. Next time you try performing in front of a filled football stadium with cameras everywhere and pull it off without messing up, call me...
