Jennifer Lopez is the world's most powerful celebrity, according to Forbes magazine Wednesday in a rankings based on a combination of earnings, press coverage and Internet presence.
Lopez headed the 100-strong list, up from 50th last year, while her American Idol colleague Ryan Seacrest was 29th. Lady Gaga, the pop singer, came in at number five, toppled from her top perch last year.
Television presenter Oprah Winfrey was second, followed by teen heartthrob Justin Bieber at third and singer Rihanna at fourth.
Many on the list at www.forbes.com/celebs showed business acumen as well as stage talent, Forbes said. For example, Bieber "is also a serious investor, with stakes in a dozen companies that appeal to his tech savvy, including a chunk of Spotify."
"Numerous celebrities are leveraging their fame to make early-stage investments or launch startups themselves," Forbes said.
The best example was J. Lo, whose acting and singing career appeared to have tanked a few years ago.
