Singer Miley Cyrus is one of the highest paid teenagers on the planet--despite not yet being old enough to drive a car.

The 15-year-old Hannah Montana star, daughter of country singer Billy Ray Cyrus, made her debut on Forbes magazine's 20 Top-Earning Young Superstars Under 25 list on Tuesday, ranking 17th with an annual income of $3.5 million.

The actress/singer looks set to rise up the list in the next year with tickets from her sold-out concert tour selling for more than $2,500 each.

Twin moguls Mary-Kate and Ashley Olsen ranked fourth after amassing $17 million each, while Harry Potter actor Daniel Radcliffe, 18, took fifth position by banking $15 million.
