Wow Oprah!!!
Nice list...

Go britney!

I think their estimate of Madonna and Oprah is conservative. I think both are richer.
I kinda think Madonna would be worth around 500million and Oprah close to 2 billion

find this
"Madonna Net Worth"

Madonna is the richest female singer in the world, and one of the richest self-made women in the world ... with an estimated net worth of over $850 million. Her wealth is closer to $850m USD than the reported $665m.
Reports about her wealth vary from programme to programme, but once all is considered, including personal wealth, real estate, and her Maverick studios earnings, Madonna just may be a billionaire herself... if not today, then very shortly in time.

In 2004 alone, she earned more than $50 million with her Reinvention Tour. Rolling Stone reported that she was worth more then $613 million dollars back in 00, and that was before her Drowned World Tour, Reinvention Tour, and The Confessions Tour. Some reports get their figures about $613 million. "On ABC’s 'Life Of Luxury' which aired on Dec. 13th 00 Madonna was named the richest female artist with an estimated fortune of $613,000,000.

The new "Guinness Book of Records" names U.S. pop star Madonna as the highest paid female singer in the world. Madonna reportedly earned about $50 million in 2004 alone, which became a new record for a female singer.

Side businesses and endorsements are another lucrative source of great income for Madonna, and with the star power, and magnitude of an artist of Madonna's caliber its worth to pay millions when you are being advertised by one of the best billboards in the world. Everyone knows that Madonna is the queen of endosement deals. Don't forget to count that along with her MadGuy Films, Boy Toy inc, Webo Girl, Siren Films, ****co inc, and Maverick films.

Maverick Records is the most successful "vanity label" in music history. While under Madonna's control it generated well over $1 billion for Warner Bros. Records, more money than any other recording artist's record label. She helped bankroll Alanis Morissette and Michelle Branch's careers.

Alvin Hall presenter of World's Most Powerful on BBC News chose Madonna as the World's Most Powerful celebrity followed by Oprah Winfrey.

jesus!!! J.Lo @ #9!! <333

Yay Oprah!

Britney could have been so much richer if she would have kept working.

Britney Spears, 25, also makes the list, despite a relatively brief career that took off only in 1999 with the release of her hit single "...Baby One More Time." Her $100 million fortune was earned largely from music--she has sold over 75 million albums to date--but she has supplemented her income with a profitable line of perfumes and multimillion-dollar endorsement deals.

That's a cute picture.

Those who believe this list need a reality check.
They even said they only named those in the news recently who have been active recently so that leaves off so many people like SHANIA TWAIN whose swiss financial reports her net wealth at 450 million. How about Cher? or Dolly Parton who owns Dolly Wood and is estimated at over 400 million.
And any list that has E entertainment connected to it is just another list that means nothing. They have no clue how much these woman make. Some keep everything private like a Shania who lives in Switzerland and some flaunt it like P diddy or Maddona or others and they want to be in the news.

I definitely believe the top 2 are accurate.

btw, martha stewart is really entertaing...

LMAO poor guy, you're trying too hard. Do you we are not stupid and we all know Shania can't be richer than Madona, Celine and Mariah ?!!!

Anyways, I didn't know Celine was that rich !lool!

Yeah Madonna and Oprah are definatly worth more than that. Like i said before on some thread, BBC estimated 2 billion. Which is probably too much, but i think thats closer than what these guys have reported.
