It doesn't count all of their total tour revenue, notice how on Britney's they only note it's based off of $21,000,000. So Rihanna made much more.
Aside from the tour, which I think still accounts a huge percentage of Rihanna's earnings for the year, one would think her massive single/album sales would compensate for the rest. She's practically ubiquitous in the same level as Gaga and Perry but her total earning doesn't translate much quite well in proportion to her popularity.
Britneys voice is very versatile.
She can reach very high and low notes.
Obviosuly shes not more talanted than Whitney was, but she does have an amazing voice, believe it or not. Her voice is more versatile than Gagas.
8 Celine Dion
$14,261,515 She grossed $40.1 million from 57 performances
Though Dion's last studio album was in 2007 she sold 331,000 albums in 2011
The singer also sold 956,000 digital tracks last year.
2 albums + 1 soundtrack = 9 Grammys, 1 Golden Globe and 1 Oscar
Trust me, I'm NEVER getting over Gaga...
You know how they say you can NEVER have too much of a good thing (sushi, sex or Gaga being the 'good thing,' because who doesn't like those things?). I was saying that sometimes too much can be too much, and you need a little break.
Mediatraffic, sweetie. Confirmed on the forum by an adminstrator. Also, another source (less reliable) is Wikipedia. It lists sales at 15 million worldwide. Please research before you go around embarrassing yourself.
