J.K. Rowling, Oprah and Others are Really Rich

Here's something almost as shocking as Rosie O'Donnell criticizing someone:

Oprah Winfrey tops Forbes magazine's current List of the 20 Richest Women in Entertainment.

Winfrey is estimated to have made $1.5 billion in her 20-plus year career, followed by Harry Potter author J.K. Rowling, 41, who has made $1 billion since Harry Potter and the Sorcerer's Stone was published nine years ago.

The only woman on the list with jail time on her record, Martha Stewart, came in third with $638 million.

Madonna ranks fourth with $325 million.

Finishing out the top ten are:

• Mariah Carey ($225 million)
• Janet Jackson ($150 million)
• Julia Roberts ($140 million)
• Jennifer Lopez ($110 million)
• Jennifer Aniston ($110 million)

The magazine also counts Ashley and Mary-Kate Olsen as one person. Which makes sense given how scary they both look.
