Britney Spears, Taylor Swift Land In Top Three Of Forbes Highest-Paid Women

'X Factor' judge narrowly beats out Swift for runner-up on the list, with Oprah Winfrey holding on to her long-held #1 spot.

Oprah Winfrey is OWN-ing this year's Forbes Entertainment's Highest-Paid Women list. But, there's a trio of pop superstars who are angling to take down the queen of talk: Britney Spears, Taylor Swift and Rihanna.

The business publication estimates that Winfrey, who is no stranger to the top of the annual list, took in $165 million between May 2011 and May 2012. But, Forbes notes that while Winfrey is ruling the roost this year, given that she has yet to earn a salary at OWN, Oprah's next chapter may not include her making the top of the list next year.

Spears settles in at #2. The "X Factor" judge raked in $58 million in the same timeframe as the talk show host. While Spears makes a reported $15 million salary from her judging spot on the show, Forbes notes that most of what she made in that timeframe came from album and Femme Fatale tour sales.

Swift follows behind with a close $57 million in revenue. The 22-year-old is the youngest person on the list thanks to her successful Speak Now tour and several hit singles, including her "Hunger Games" track, "Safe & Sound." Swift is set to release her new album, Red, this month, riding off the success of its first single, "We Are Never Ever Getting Back Together," which spent three weeks at the top of Billboard's Hot 100 chart.

The #4 spot is occupied by two women. Rihanna and Ellen DeGeneres both land there with an impressive $53 million. Rihanna finds herself tied with DeGeneres thanks to her social media presence while the talk show host seems to be making a play for Winfrey's empire, having expanded her brand to include launching talk shows (like she has with Bethenny Frankel) and serving as the face for J.C. Penney.

Lady Gaga tied with former "American Idol" judge Jennifer Lopez for the #5 with a $52 million revenue. Gaga's Born This Way album and tour helped her rake in the big bucks, as well as taking on several social causes (like her recently launched Body Revolution 2013 campaign).

Supermodel Gisele Bundchen ($45 million), Katy Perry ($45 million) and TV's Judge Judy ($45 million) round out the list.
