Listen to Lady Gaga on iHeartRadio | Listen to Justin Bieber on iHeartRadio

Despite being sidelined by a hip injury for a good part of the year, Lady Gaga has managed to earn the top spot on "Forbes'" latest "Highest-Earning Celebs Under 30" list. 

According to the magazine, the Mother Monster brought in $80 million between June 2012 and June 2013.  Her "Born This Way Ball" tour reportedly grossed a total of $168 million when it was cut short in January, and the magazine predicts that it likely would have topped the $200 million mark had she been able to finish it. 

Justin Bieber was the runner-up this year.  The 19-year-old earned $58 million, courtesy of his "Believe" tour and chart-topping "Believe Acoustic" album.  

Taylor Swift came in third, followed by Calvin Harris, Rihanna, Katy Perry and Adele.  Actors Jennifer Lawrence, Kristen Stewart and Taylor Lautner all made the list's top ten as well.
