A recent survey found that more half of American women were considered the primary breadwinners in the family. So CelebrityBabyScoop.com looked at 10 celebrity moms who cash in at higher levels than their partners.

Jessica Alba
Mom of daughters Honor, 4, and Haven, 1, Jessica Alba has an estimated net worth of $20 million. While her husband Cash Warren is a Yale graduate and film producer, Jessica rakes in millions for her movie roles, and is now the co-owner of the Honest Company. But Jessica is sure to give her lower-earning husband credit for her ongoing success. “My husband Cash has been integral in my development as an entrepreneur,” she said.

Bethenny Frankel
Former "Real Housewives of New York" star and SkinnyGirl Cocktails founder, Bethenny Frankel, pulled in a cool $12 million last year. The television star and entrepreneur -- mom of 3-year-old daughter Bryn -- has an estimated net worth of $25 million. Bethenny’s estranged husband, Jason Hoppy, has a much lower income as a pharmaceutical rep.

Gwen Stefani
British rock star Gavin Rossdale and his band, Bush, broke up in 2002. But his rocker wife,Gwen Stefani, continues to be the frontwoman of No Doubt. And not to mention, she created her successful clothing line, L.A.M.B. In 2008 alone, the mom-of-two earned $27 million. With an estimated net worth of $80 million, the mom of Kingston, 7, and Zuma, 4, really knows how to rake in the dough.

Drew Barrymore
With her acting career and successful production company Flower Films, Drew Barrymore earned $12 million in 2009. And her estimated net worth is a whopping $125 million. Although Drew’s new husband, Will Kopelman, is an art adviser and no stranger to wealth (he is the son of former Chanel CEO Arie Kopelman), his paychecks pale in comparison to his famous wife. The pair are new parents to 7-month-old daughter Olive.

Reese Witherspoon
With an Academy Award and numerous hit movies under her belt, it’s no surprise that Reese Witherspoon -- mom of Ava, 13, Deacon, 9, and Tennessee, 7 months -- has an estimated net worth of $80 million. While she was once wed to fellow actor Ryan Phillippe, and recently dated fellow A-lister Jake Gyllenhaal, she is now married to talent agent Jim Toth, who does not earn multimillion dollar paychecks like his famous wife.

Jessica Simpson
Jessica Simpson is one of the most famous singer-turned-entrepreneurs of all time.
The expectant mama has a lucrative fashion line, a Weight Watchers deal and a hosting gig on TV’s "Fashion Star," making her estimated net worth around $100 million. Meanwhile, her fiancé Eric Johnson, a former NFL player, is not bringing home any known revenue at the moment. The couple expect their second child within weeks, and they are already parents to 1-year-old daughter Maxwell.

Kelly Ripa
She’s a former soap star that turned into a successful talk show host, holding her own next to the king of daytime TV, Regis Philbin. But Kelly Ripa -- lucky in love after 17 years of marriage to her "All My Children" co-star Mark Consuelos -- is also incredibly wealthy, worth an estimated $75 million. With Mark taking on the occasional hosting gigs, Kelly rakes in the dough for Mark and their three kids: Michael, nearly 16, Lola, nearly 12, and Joaquin, 10.

Natalie Portman
Academy Award-winning actress Natalie Portman has been called one of Hollywood’s most “bankable” actresses. Her husband, ballet choreographer Benjamin Millepied, recently landed the new role of director of Dance at the Paris Opera Ballet. But Natalie -- mom to 1 1/2-year-old Aleph -- is still the main breadwinner, with an estimated net worth of $32 million.

Mariah Carey
Nick Cannon reportedly receives $70,000 per episode of "America’s Got Talent." But that does not even compare to his wife, Mariah Carey, and her reported $18 million salary to join "American Idol." As one of the most successful female recording artists of all time, Mariah is worth an estimated $500 million, making her more than capable of providing a luxurious lifestyle for the couple’s 2-year-old twins Moroccan and Monroe.

Julia Roberts
"Pretty Woman" star Julia Roberts was ranked the fifth highest-paid actress by Forbes in 2011 and regularly pulls in double-digit figures for her movies. After meeting on the set of 2001?s "The Mexican," Julia and her hubby, cameraman Danny Moder, have welcomed three children: 8-year-old twins Finn and Hazel and Henry, 6.
But although Danny also works in the film industry, he doesn’t even come close to his wife’s estimated net worth of $140 million.
