1. Madonna
$72 million

The ever-morphing singer still outsells artists half her age. She tops the Cash Queens list thanks largely to her record-breaking Confessions tour, plus income from album sales, an apparel line with retailer H&M and a deal with NBC to air concert footage

2. Barbra Streisand
$60 million

The 65-year-old legend, with 145 million albums sold worldwide to her credit, drew legions of die-hard fans to her short (and rare) concert series that wrapped in Europe last summer. Some tickets sold for upward of $1,000 apiece.

3. Celine Dion
$45 million

The Canadian diva's landmark Las Vegas concert drew some 3 million fans and grossed upward of $450 million during its five-year run, which ended in December.

4. Shakira
$38 million

The Colombian chanteuse shook her trademark hips from Mexico to India on a tireless tour that saw her perform 111 concerts before it was over.

5. Beyoncé
$27 million

The former Destiny's Child front woman is an endorsement darling, boasting deals with blue-chip brands like American Express, L'Oreal and Samsung.

6. Gwen Stefani
$26 million

Her last album, The Sweet Escape, peaked at No. 3 on the Billboard charts, her best performance as a solo artist. The 38-year-old platinum blonde also has an endorsement deal with HP, her own fashion label and a recently launched fragrance.

7. Christina Aguilera
$20 million

Critics adored the retro stylings of Back to Basics, her third studio album, which also proved popular with fans. Aguilera also inked deals with Pepsi and Orange, a European cellphone operator. In January, the 27-year-old welcomed her first child, Max.

8. Faith Hill
$19 million

Country's beauty-queen crooner joined husband Tim McGraw on the road for the Soul2Soul II tour, one of the year's fastest-selling, top-grossing American concert series, beating out even the U.S. leg of Madonna's Confessions tour. Hill also belts out NBC's Sunday Night Football theme song.

9. Dixie Chicks
$18 million

Despite vehement criticism from country fans of their anti-war, anti-Bush politics, the Dixie Chicks proved their resilience with their seventh studio album, the Grammy-winning Taking the Long Way Home. Though it immediately topped country and pop charts, the tour to promote the album was hit-or-miss. The Chicks canceled dates in Texas and Oklahoma following refusals from several radio stations to advertise the event.

10. Mariah Carey
$13 million

The 37-year-old pop and R&B diva makes good money off of her extensive catalog. (Her 10 studio albums have sold over 100 million copies worldwide.) The musical director for her last tour, dubbed The Adventures of Mimi, was longtime collaborator Randy Jackson, judge of American Idol.

11. Hilary Duff
$12 million

The 20-year-old former child star of Disney's Lizzie McGuire has quickly established herself as a credible pop star thanks to Dignity, her modestly selling recent studio album. Though acting and music may be her passions, retail is her biggest moneymaking asset. Stuff by Hilary Duff, merchandise targeting her tween fans, is available at Kohl's and JCPenney.

12. Avril Lavigne
$12 million

Marriage hasn't slowed this 23-year-old rocker down. Her third studio album, The Best Damn Thing, topped the pop charts last year and spawned an international mega-hit from its first single "Girlfriend." The video for that song is the second most-watched clip on YouTube, with over 69 million views. Lavigne recorded the chorus to the song in seven other languages, including Mandarin and German.

13. Martina McBride
$12 million

The 41-year-old country crooner's ninth studio album, Waking Up Laughing, was an unlikely crossover hit last year, earning top 10 spots on the country, adult contemporary and Hot 100 charts. (She's still on the road promoting the album on tour.) She and her husband own and operate Nashville's Blackbird Studio, where A-list music acts like John Bon Jovi and Keith Urban have recorded.

14. Britney Spears
$8 million

The former pop-superstar-turned-tabloid-staple eeks out a sizable income from her catalog of hits--the 26-year-old has sold over 80 million records worldwide over the course of her career--and royalties from sales of her fragrance lines. Critics be damned, her latest album, Blackout, has been a modest hit.

15. Carrie Underwood
$7 million

American Idol's fourth-season champ saw her debut album, Some Hearts, sell 8 million copies worldwide and spawn a mega-hit of its third single, "Before He Cheats." (Over 2 million downloads and counting.) Her sophomore effort, Carnival Ride, has sold over 2 million copies. Word is she'll hit the road this year with Keith Urban to promote their respective albums.

16. Nelly Furtado
$7 million

The one-time folk-indie-songstress-turned-pop-star partnered with uber-producer Timbaland for her third album, Loose, said to have sold more than 7 million copies worldwide. The album launched eight hit singles, including "Promiscuous." Furtado, 29, also appeared in Timbaland's "Give It To Me" single with Justin Timberlake

17. Fergie
$6 million

The Black Eyed Peas singer scored big with her debut solo album The Duchess, which landed five hit singles, including "Glamorous" and "Big Girls Don't Cry." Born Stacy Ann Ferguson, the 32-year-old also bagged endorsements with Kipling bags and Candie's shoes.

18. Jennifer Lopez
$6 million

Despite weak album sales of her first Spanish-language album Como Ama una Mujer and limited touring, J.Lo still rakes it in, mostly from her catalog, clothing sales and incredibly successful fragrances. (There are six fragrances so far.) Lopez also collected a paycheck for her credit in El Cantante, the biopic of salsa star Hector Lavoe co-starring hubby Marc Anthony. Lopez, 38, who also runs her own production company, is reportedly expecting twins.

19. Sheryl Crow
$6 million

The nine-time Grammy-winning pop-rock singer enjoyed income from her catalog and a smallish 2006 tour to promote her last album, Wildflowers. During that period, Crow overcame a breast cancer diagnosis and endured a very public breakup with Lance Armstrong. Last year she adopted a son, Wyatt Steven. In February, Crow, 45, will release Detours, her sixth studio album

20. Norah Jones
$5.5 million

The 28-year-old mellow rocker released her third album, Not Too Late, earlier this year and has reportedly sold 3 million copies worldwide to date. She also enjoyed income from a worldwide tour to promote the album. This year she'll make her big screen acting debut opposite Jude Law in My Blueberry Nights.
