She said the first two notes/keys.

Which was the 'oooooooohhh ahhhh'
which I personally think was pointless, and kinda stupid to add to the song.

I don't believe she was bitchy, it was criticism, and true criticism at that.
It's not like she said the performance was rubbish, that would be unnecessary.
Presumably the Hope girls will learn from it.
