have you ever performed for over 20k people? with all of them screaming at once? even the most well seasoned of performers can stumble over words when they can barely hear themselves think like that
I don't like the girl but this isn't that uncommon / it's really not a big deal. Plenty of stars use visual cues for their own lyrics.
Miley, Taylor, Elton John, Beyonce, Prince, etc all do it but this one is obviously photoshopped.
Actually no. I was standing in the reflection section, in the front and my friend who is very tall saw it he even took and showed the rest of us. It was the lyrics for Roar. So no, that one is not fake.
