With income of $59 million so far this year, Lady Gaga has nabbed the No. 4 spot on Forbes’ list of 2015's highest-earning female celebrities. Forbes officially released the “2015 Celebrity 100” on Monday. It lists the world’s top-earning celebrities based on annual income.

The “Born This Way” singer was not able to top Katy Perry, who nabbed the No. 1 spot for top-earning female musicians. Over the past year, Gaga has been known to surprise her fans with brave music choices. In September 2014, the “Paparazzi” singer partnered with crooner Tony Bennett, releasing their “Cheek to Cheek” duet album, which features jazz standards. To promote the Grammy-winning album, the two went on a world tour that includes a European leg this summer.

Gaga also has several endorsement deals and business ventures in her portfolio. She is the face of the Versace fashion brand and has even landed a deal with MAC Cosmetics, along with launching her own fragrance line named “Fame.” The singer is also known for her edgy and over-the-top fashion choices, which usually become hot topics among the media and fans alike.

Gaga made headlines with her fashion choice last week, while in New York City for a series of performances. After finishing off a “Cheek to Cheek” show with Tony Bennett at Radio City Music Hall and serenading fans in an intimate concert at the SixtyFive club, the singer suffered a wardrobe malfunction while exiting a pizza joint, Us Weekly reported, inadvertently flashing her left breast to the public.

Meanwhile, Perry topped the Forbes list with earnings of $135 million. Other women on the list, according to Hello!, included Taylor Swift with $80 million, Ellen DeGeneres with $75 million and Beyoncé, who made $54.5 million.

Lady Gaga came in at No. 25 among all celebrities, male and female, topping male artists such as Jay Z, Ed Sheeran, Bruno Mars and others.
