Coming off a concert tour, a hit 3-D movie and a risqué picture in Vanity Fair, pop star Miley Cyrus (a.k.a. Hannah Montana) leads a slew of young stars onto our annual Celebrity 100 ranking of the world's ultrafamous. Also building buzz, and drawing dollars, from the under-18 crowd: Daniel Radcliffe, Zac Efron and Ashley Tisdale.

Despite weakening television ratings and magazine circulation, Oprah Winfrey remains at the top of the list, a power ranking based on both earnings and fame. The biggest earner: J.K. Rowling, whose final installment of the wizardly adventures of Harry Potter helped add $300 million to her coffers, solidifying her status as the richest author on the planet.

Ranks 26 - 100 here.
