Lady Gaga has beaten fellow pop stars Justin Bieber, Taylor Swift and Rihanna to be crowned the most successful celebrity under 30.
The 27-year-old Poker Face songstress, whose real name is Stefani Germanotta, came up top in the Celebrity 100 list, compiled by Forbes.com, after banking an estimated 80 million US dollars in the past year from her Born This Way Ball world tour.
The tour made around 168 million US dollars and she would reportedly have made up to 200 million US dollars if she hadn't suffered the hip injury that curtailed the rest of her live dates.
Savvy Canadian star Justin took second spot, making around 58 million US dollars with stakes in start-ups including Enflick, Tinychat and Spotify, followed closely by Taylor, who reportedly earned around 55 million US dollars from the sales of her fourth album Red and her endorsements with brands such as Diet Coke, Sony and Covergirl.
Females dominate this year's list, with seven of the top ten being women.
British stars didn't fare too badly with Scottish DJ-producer Calvin Harris taking fourth place and Adele coming in the seventh position.
Forbes.com writer Dorothy Pomerantz said: "It's somewhat ironic that Lady Gaga once again ranks as the top-earning celebrity under the age of 30. This year the singer underwent an experience usually reserved for old people: hip surgery. Most of the women on our list are pop stars who earn just as much as their male counterparts."
