Her job as a judge on "American Idol" may not have worked out, but it's unlikely that Ellen DeGeneres is singing the blues. That gig helped the comedian land the top spot on Forbes's list of Prime-Time TV's 10 Top-Earning Women.

According to Forbes, DeGeneres raked in an estimated $55 million between June 1, 2009 and June 1, 2010, thanks to her brief stint on "Idol," her ads for American Express, CoverGirl and Vitamin Water, as well as her daytime chat show.

Coming in at No. 2 is Tyra Banks, who banked $25 million within the same time frame. Besides producing and appearing on "The Tyra Banks Show" and "America's Next Top Model," Banks also produced ABC's reality show "True Beauty" and recently signed a deal to release a teen book series called "Modelland."

Former "Grey's Anatomy" star Katherine Heigl comes in third with a cool $15.5 million, owing many of her megabucks to her success on the big screen. Because of hits like "Knocked Up" and "27 Dresses," Heigl, who co-stars with Josh Duhamel in the upcoming dramedy "Life As We Know It," now commands $12 million per picture.

Rounding out the rest of the list of gals who are in the green: Eva Longoria Parker ($12 million); Marg Helgenberger ($10 million); Mariska Hargitay ($9.5 million); Tina Fey ($7.5 million); Ellen Pompeo and Marcia Cross (tie; $7 million); and Jennifer Love Hewitt and Calista Flockhart ($6.5 million).
