Lady Gaga is proving she's a force to be reckoned with in more ways than just music - she's quickly becoming one of the richest female stars in the world.
The Poker Face hit-maker has enjoyed a meteoric rise to fame since hitting the charts in 2008, and she is now rocketing up the rich list thanks to her best-selling debut album The Fame and sell-out Monster Ball tour. Gaga is fourth in Forbes magazine's 2010 list of the richest women in Hollywood, raking in $64 million over the last 12 months.
She is only beaten by rich list regulars Oprah Winfrey - who outstrips all rivals with earnings of $324 million - Beyonce and Britney Spears, who have pulled in $89 million and $65 million respectively in 2010.
Following Gaga in fifth place is her idol Madonna, who has made an impressive $59.9 million, while Sandra Bullock has her Oscar win to thank for helping her earn $59.2 million.
TV talk show host Ellen DeGeneres, Miley Cyrus, Taylor Swift and Judge Judy round out the top 10 wealthy women in Hollywood.
