However, despite putting on an energetic show, the singer's performance left some doubt as to the state of her mental well-being.

The singer later continued her strange antics, throwing a microphone worth thousands into the crowd after it failed mid set.

Perhaps she was trying to give audiences their money's worth as the singer reportedly commanded a surprising 65,000 euro  fee for the show at the Electric Arena in Ireland.
