Here's who made the profitable list:
Kim Kardashian: $6 million
Keeping up with this Kardashian is no easy feat. Aside from her popular reality show, Kim has made a fortune selling everything from cupcakes to Quick Trim. The star's latest endeavor: a new book Kardashian Konfidential.
Lauren Conrad: $5 million
She said goodbye to The Hills two years ago, but LC has continued to reap the riches of being a reality superstar. She's written a trilogy of young adult novels and a style guide, but it's her highly successful fashion line for Kohl's that turns the biggest profit.
Bethenny Frankel: $4 million
Frankel stole the show from her fellow Housewives of New York City and walked away with her own series, Bethenny Getting Married. But it's her SkinnyGirl products (margaritas and books) that have made her wallet fat.
Audrina Patridge: $3.5 million
She started off as the sweet sidekick on The Hills, but became a star in her own right after Lauren Conrad's departure and Heidi Montag's meltdown. Next year Patridge will headline a new reality show on VH1.
Kate Gosselin: $3.5 million
Kate is doing just fine minus Jon. The mother of eight reportedly gets paid $250,000 an episode and has raked in a significant sum from her book deals.
Mike "The Situation" Sorrentino: $3 million
"The Situation" has taken GTL-ing straight to the bank. Aside from being Jersey Shore's highest paid cast member, Sorrentino has become quite the entrepreneur. He's written a book, released fitness DVDs and is working on his own cologne.
Rounding out the top 10: Khloe and Kourtney Kardashian, DJ Pauly D and Kendra Wilkinson.
