Jennifer Lopez has topped the annual Forbes list of the 100 most powerful celebrities in the world, taking over from fellow pop singer Lady Gaga and beating out media mogul Oprah Winfrey.

The 42-year-old singer, actress and dancer, who rose up through the entertainment world ranks from her humble birthplace of the Bronx, New York, surprisingly jumped from 50th place on last year's list that measures power by entertainment related earnings, media visibility and social media popularity.

Forbes estimated Lopez' earnings in the past 12 months at $52 million (32.67 million pounds), and her top ranking is powered by her lucrative gig as a judge on popular television show, "American Idol," a new clothing line at Kohl's, a top-selling fragrance and millions of Twitter and Facebook followers. She also just announced her first upcoming world tour, joined by Enrique Iglesias.

Winfrey, who has admitted struggling with her OWN TV network after ending "The Oprah Winfrey Show" syndicated TV chat show last year after 25 years, kept her No. 2 slot from last year, earning an estimated $165 million.

Canadian pop star Justin Bieber, 18, also stayed at No. 3 where he debuted last year, earning $55 million, with Forbes reporting he has become a serious investor whose portfolio includes music streaming service Spotify.
