Oprah Winfrey takes back her crown while pop chart phenomenon Lady Gaga catapults to No. 4 on this year's Celebrity 100. Pants-less pop stars, late-night warriors and sexy vampires spiced up the fame game last year, with Lady Gaga, Conan O'Brien and Twilight superstars Kristen Stewart and Robert Pattinson joining the Forbes Celebrity 100 list for the first time. But despite their impressive debuts (Gaga hit the list in fourth place), Oprah Winfrey is the year's big winner. After being ousted by Angelina Jolie on last year's list (Jolie dropped to No. 18 this year), the Queen of all Media takes back her crown on Forbes' annual ranking of the world's ultra-famous.

Lady Gaga catapults onto our list, ranking ahead of much more established pop stars like Madonna (No. 10) and U2 (No. 7). She has a 106-date world tour and her willingness to partner with corporations like Virgin Mobile and Polaroid to thank for an estimated $62 million in earnings. What's more, her fame and theatricality have brought her gobs of press coverage, while her music videos have made her something of an Internet sensation. Proof: The fashion-forward rocker ranks first for social media and Web presence among the Forbes Celebrity 100.

Gaga is also the list's top-ranked newcomer, leading a group that includes the Black Eyed Peas ($48 million), O'Brien ($38 million) and Twilight costars Pattinson and Stewart. Pattinson comes in at No. 50 with estimated earnings of $17 million, while Stewart, who is working on fewer non-Twilight projects, comes in at No. 66 with a $12 million haul.

Gaga is #1 in Web AND Social rank. She owns the interwebz pretty much. Gaga is Beautiful. Dirty. Rich.
