Congratulations, Taylor Swift! The musician topped Forbes's list of the highest-paid celebrities under 30, followed by Justin Bieber, who came in a close second. Swift earned over $57 million between May 2011 and May 2012, and a good portion of that money came from her Speak Now world tour, for which she made $1 million per night. Rihanna, Lady Gaga, and Katy Perry rounded out the top five, proving it pays to be a pop star.
