Reece is raking it in

She may have starred in a movie about the life of JOHNNY CASH, but it seems REESE WITHERSPOON is one with all the money.

The Walk The Line star is officially Hollywood's highest paid actress, according to a new study.

The Legally Blonde star pulls in an estimated US$15 to $20 million per film, putting her at the top of the new Hollywood Reporter rich list.

This means the mum-of-two, who is currently dating JAKE GYLLENHAAL, earns more than Hollywood heavyweights CAMERON DIAZ and NICOLE KIDMAN.

Renee Zellweger, Halle Berry and Julia Roberts also make the new trade top 10.

The full list is:
1. Reese Witherspoon - $15 million-$20 million
2. Angelina Jolie - $15 million-$20 million
3. Cameron Diaz - $15+ million
4. Nicole Kidman - $10 million-$15 million
5. Renee Zellweger - $10 million-$15 million
6. Sandra Bullock - $10 million-$15 million
7. Julia Roberts - $10 million-$15 million
8. Drew Barrymore - $10 million-$12 million
9. Jodie Foster - $10 million-$12 million
10. Halle Berry - $10 million
