Who makes more money Beyonce or Shakira?

Shakira is a better belly dancer becaus she does that professionally and has done since she was 4 years old. Beyonce said in an interview that Shakira taught her belly dancing for the video 'Beautiful Liar'. However I have watched one of Beyonce's live DVDs and she is also a very good dancer. But the dancing Shakira and Beyonce are best at are both completely different! So it's hard to judge who is better.
