Who is closer to be the next Queen of Pop?

Beyonce IS the queen of pop and rnb.... Until Gaga can prove that she has longevity (make an album in 15 years) then will talk. Its HONESTLY between Beyonce and Britney. They;ve both been in the game since their teen years. They both can sell out concerts all across the world. Now if we took it to the next level and said who sings live then Beyonce automatically wins. Queen of Pop goes to someone who is multi-talented. Not put the track and and move your lips. Shakira shouldn't even be on the list lmao.... Rihanna idolizes Beyonce and so far she cannot sell out concerts worldwide.
