It is the year of the tween. Coming off a massive concert tour, a hit 3-D movie--and a risqu� picture in Vanity Fair--pop star Miley Cyrus (aka Hannah Montana) leads a slew of young stars onto Forbes' annual Celebrity 100 ranking of the world's ultra-famous.

Also building buzz, and drawing dollars, from the under-18 crowd were Harry Potter [Images] star Daniel Radcliffe [Images], teen crooners the Jonas Brothers and High School Musical stars Zac Efron and Ashley Tisdale.

Oprah Winfrey remains No. 1 on the Celebrity 100, a power ranking based on both earnings and fame. Despite weakening television ratings and magazine circulation, Winfrey earned 11,786.5 billion rupees before taxes in the past 12 months, and she remains one of the most famous faces in the world.

The Celebrity 100 is Forbes' list of the world's most powerful--and best-paid--celebrities. To generate the list, Forbes estimates celebrity earnings, then factors in media metrics like Google hits, press mentions as compiled by Factiva, TV/radio mentions from Lexis/Nexis and the number of times an A-lister appears on the cover of more than 50 consumer magazines.

Earnings estimates are for June 2007 to June 2008 and consist of dollars earned solely from entertainment-related income. Management, agent and attorney fees are not deducted.

Golf star Tiger Woods [Images] retained the No. 2 spot on the list, raking in Rs 4,928.9 billion on and off the course, while actress Angelina Jolie [Images] soared to the third spot, combining Rs 600.0 million in earnings with unrivaled levels of fame.

Another power couple in the top 10: pop star Beyonce Knowles [Images] (No. 4) and hip-hop mogul Jay-Z (No. 7). Beyonce had a monster year, pulling in Rs 3,428.8 billion between a highly successful concert tour, private shows, a fashion line, endorsement deals and film work.

Jay-Z left Def Jam Records to sign a Rs 6,429 billion deal with concert promoter Live Nation. The deal provides the rapper and entrepreneur with money for recording, tours and other entertainment endeavors for the next decade.

Will Smith [Images], ranked 11th, is the highest paid actor in Hollywood, bringing home Rs 3,428.8 billion, including an estimated Rs 857.2 million for his role in the upcoming anti-superhero flick Hancock.
