Rihanna has helped raise over a million dollars for Unicef. She also just recently held a benefit concert for the tornado victims in AL where 100% of the proceeds went to them. She also has DKMS and is a spokeswoman for the American Cancer Society.

Shakira has given more than half of this list.

They tried.

I volunteer weekly at my local free health clinic.

They've underestimated gaga on this. Didn't she also give a percentage of profits on the monster ball to charity nightly? Wasn't it to homeless gay or lesbian youth or something? I forget.

Of course the lovely madonna is on here. How could she not be?

Correct. Through the Virgin mobile program, she donated like $20k each night.
