The pop princess already made headlines after scoring a Las Vegas residency last year and inking nearly $30 million for two years in her contract, but because Spears' "Pieces of Me" show has already surpassed everyone's expectations during its first run, Brit Brit is now going to make even more dough.
How much more, you ask? Well, according to a source, E! News is told that instead of her current ballpark of $310,000 a show, Britney will begin earning around $475,000 a show! (FYI: Céline Dion makes a thousand more than that per show.)
