Lady Gaga has been named the highest-earning woman in music with an estimated income of more than $90 million.
The pop superstar has come top of a list of 2011's wealthiest female stars compiled by America's Forbes magazine, which put Gaga's earnings down to lucrative endorsement deals and her long-running world tour.
The Poker Face star's nearest rival is country singer Taylor Swift, who came second in the list by bringing in approximately $45 million over the last 12 months. Swift is closely followed by pop star Katy Perry in third with $44 million.
