Will.I.Am sit your ass DOWN, and stop try to sing...
Not her forgetting the step on Call My Name, she killed it vocally on CMN but 3 words was not that good, she can do better.
She didn't forget the steps, it was the outfit that wasn't prepared for the performances. She had another outfit but there was a problem with it so she performed with the one she did the red carpet and the interviews.
Looks like she was singing it all live. Hopefully the massive **** up at the Stand Up To Cancer show made her realise she needs to sing live more or she risks just embarrassing herself more. Anyway she was great, but I agree the outfit probably meant she held back in terms of the dancing.
