Top 10 Most Powerful Stars

See where Oprah Winfrey, Taylor Swift, Justin Bieber, and more land on the 2013 edition of Forbes's annual Celebrity 100 list.

       #10 Ellen DeGeneres The star and executive-producer of the daytime talk show hit "The Ellen DeGeneres Show," now in its 10th year and drawing 3.5 million viewers daily, will soon be back on the silver screen. She recently signed on to "Finding Dory," a reprise of her role as a charmingly forgetful blue tang fish in Disney-Pixar's $921 million grossing film "Finding Nemo." The 55-year-old CoverGirl is also a social media superstar. Her YouTube channel's 1.7 billion views and 18 million Twitter followers have made her a hit with young viewers.

     #9 Justin Bieber Since appearing on the cover of Forbes last year, the Canadian crooner has toured the world, picked up another 20 million Twitter followers, and earned another $58 million (that sum would have been even higher if we hadn't credited him with a double-digit million-dollar merchandise advance last year). With stakes in startups including Enflick, Tinychat, and Spotify, he shows no signs of slowing down.

      #8 Roger Federer Federer has the most impressive endorsement portfolio in sports, with 10 sponsors that collectively pay him more than $40 million annually, including long-term deals with Nike, Rolex, Wilson, and Credit Suisse. The newest addition is champagne brand Moet & Chandon, which signed Federer to a five-year deal at the end of 2012. Federer's income surged after a barnstorming exhibition tour of South America that netted him $14 million for six events. Why so much? Federer is widely perceived as the greatest tennis player ever. He holds the records for most singles Grand Slam wins (17) and career prize money ($77 million), and he appeared in a staggering 18 out of 19 Grand Slam finals between 2005 and 2010.

      #7 Bon Jovi (the band) The ageNew Jersey rockers said it best themselves: Because We Can. That's the name of their latest stadium tour, which is grossing over $3 million per city as they crisscross the globe. All in all, they earned more than Kanye West, Jennifer Lawrence, and Rafael Nadal combined and continued to give back. Last fall, frontman Jon Bon Jovi celebrated the one-year anniversary of the Soul Kitchen, a pay-what-you-can restaurant in Red Bank, N.J.

    #6 Taylor Swift Who says the music industry is dead? Swift released her fourth studio album, "Red," in October 2012 and sold 1.2 million copies in week one. The album's first single, "We Are Never Ever Getting Back Together," became her first to top Billboard's Hot 100 chart. She parlayed that success into endorsement deals with Diet Coke, Sony, and CoverGirl, not to mention big bucks on the road. She should earn even more next year as she transitions from arena shows to stadium sellouts.

     #5 Madonna The "Material Girl" is once again living up to her moniker, earning more than any other member of our Celeb 100. The cash comes mostly from her MDNA Tour, which grossed $305 million, earning her the Top Touring Award at the Billboard Music Awards. Madonna augments her income with heady merchandise sales at concerts as well as her Material Girl clothing line, Truth or Dare fragrance, and investments in coconut water company Vita Coco and others.

    #4 Beyonce Knowles After taking a year off to welcome baby Blue Ivy into the world, Beyoncé is back on the road with her Mrs. Carter Show World Tour — a nod to husband Jay-Z, whom she out-earned once again — and makes it back to the upper reaches of our list. In addition to grossing over $2 million in every city she plays, she still collects cash from old hits and non-musical ventures including new deals with Pepsi and H&M, as well as her House of Dereon clothing line.

    #3 Steven Spielberg With last year's "Lincoln," Spielberg showed why he's still the most important director in Hollywood. The political tale easily could have been passed over by moviegoers hungry for superhero action. Instead, the film was a hit earning $275 million globally. surprising was the movie's 12 Oscar nominations including one for Spielberg. But he's more than just a director. Last year, Spielberg executive produced "Men in Black 3," and his DreamWorks is still trying to make a go of it in television, even though "Smash" was recently canceled by NBC.

    #2 Lady Gaga The Queen Monster would have earned even more had it not been for a hip injury that cut her Born This Way Ball tour short. The tour grossed $168 million through January; had Gaga been able to finish it, she would have likely topped $200 million. Even so, her massive social media presence, including 38 million Twitter followers and 58 million Facebook fans, helps keep her near the top of our list. With a new album in the works, look for her to stay there.

   #1 Oprah Winfrey Despite a drop of more than half her income since her talk show went off the air in 2011, the queen of entertainment is back in the top spot thanks to earnings from Harpo-produced TV spin-offs (such as "Dr. Phil," the "Rachael Ray Show," and "The Dr. Oz Show"), as well as her unparalleled access to big names. The world's only African-American billionaire has attracted stars from Lance Armstrong to Rihanna for sit-down confessionals on her OWN network, a joint venture with Discovery Communications which looks set to turn a profit by the end of 2013. Winfrey's portfolio also includes a deal with Sirius radio network and O: The Oprah Magazine.
