Gaga and no one comes close to her.
Gaga is the ONLY current pop girl who has massive fanbases on every habitable continent. She is the only current pop girl who is used by Asia, she's the only current pop girl who can sell out stadiums EFFORTLESSLY in places her album "flopped". Her reputation alone keeps her at the top.
You can't compete with facts and you definitely can not compete with Yoko Ono saying she's the most famous girl in the world.
