R+B superstar Mariah Carey knows nothing about maths or physics - despite naming her new album after the world's most famous equation.
The Hero hitmaker is currently promoting her new LP E=MC2, but admits she has no clue about Einstein's theory of relativity, because she was terrible at her studies.
She says, "In school I was so bad at maths that I couldn't even pass the simplest course.
"I was so crap. They wouldn't let me study any foreign language either."
