From the days of Rudolph Valentino, Judy Garland, and young Frank Sinatra, teen idols have been big business — and thanks to the latest edition of PEOPLE magazine’s richest teen celebs list, we know business is still booming.

The names on PEOPLE’S list shouldn’t surprise anyone who pays attention to pop music — the biggest teen earners include Nick Jonas, Willow and Jaden Smith, and Selena Gomez. And at the top? Justin Bieber and Miley Cyrus, of course.

Bieber took the crown, pulling in $53 million during a year that saw him popping up on the road, on TV, and — thanks to his ‘Never Say Never’ concert film — in theaters. Miley was close behind, earning $48 million from projects like her Gypsy Heart tour.

Bieber and Cyrus’ earnings far outpaced their peers — Nick Jonas took in $12.5 million, while Bieber’s lady love, Selena Gomez, topped out at $5.5 million. Let’s hope those kids are investing wisely!
