The third installment of “The Twilight Saga” premieres on Wednesday, but already Robert Pattinson and Kristen Stewart are two of the world’s most powerful celebrities, according to Forbes Magazine.

The on-screen couple, who are rumored to be a pair off-screen as well, debut on the coveted list for the first time, with Robert taking spot #50 and Kristen trailing at #66.

Oprah Winfrey, who was trumped by Angelina Jolie last year, reclaimed her #1 spot on the annual Forbes list with earnings of $315 million.

Other newcomers to the list included Lady Gaga who appeared in the #4 spot with earnings of $62 million, as well as James Cameron who thanks to “Avatar” earned #3 spot with $210 million in earnings.

Additional first time appearances included Conan O’Brien (#51), the Black Eyed Peas (#16), Robert Downey, Jr. (#73), and Chelsea Handler (#98).

Sandra Bullock, who had a rough year in her personal life, scored high on the list professionally, earning the #8 spot with $56 million in earnings.
