No woman in country music can match Taylor Swift's 2010 income. In fact, there are very few women in America who can top the country star. Swift earned $45 million, enough to put her fourth on Forbes Magazine's list of Entertainment's Highest Earning Women.

Tied with Swift are super model Gisele, talk show host Ellen DeGeneres and Judge Judy. Only Bethenny Frankel ($55 million), Lady Gaga ($90 million) and Oprah ($290 million) made more money. The list ranks incomes from May 2010 to May 2011.

"Swift, at only 21, has become a music-industry force to be reckoned with," the magazine reads. "Her latest album, 'Speak Now,' has sold five million copies. She was recently listed in the Guinness Book of World Records as the female with the  most simultaneous hits at once in the top 100."

Toby Keith topped Swift on Forbes' list of Country Music's Highest Stars, earning $50 million during the same time period. Carrie Underwood is the next closest female on the list, making $20 million.
