Meet the most powerful celebrity in the world.

Jennifer Lopez.

Last year it was Gaga. This year it’s JLo.

Jennifer Lopez has been named by Forbes magazine as the most powerful celebrity in the world… Meaning she’s more powerful than Oprah (who ranked #2), Justin Bieber (#3) and Rihanna (#4).

We didn’t see a lot of Jennifer Lopez for a few years, but she’s been back on the scene recently promoting her new movie What to Expect When You’re Expecting and rocking the red carpet along the way. Then there’s also her new relationship with 25-year-old back-up dancer Casper Smart, who she brought along to the movie premiere last week.

But it’s 42 year-old JLo’s relatively recent role as a judge on American Idol that said to have made her so “powerful”.  (The list is based on earnings, press coverage and internet presence).

But there’s rumours the Jenny from the Block singer might not be a judge for much longer after she hinted she might be leaving the show during an interview with Ellen DeGeneres this week.

“I really do enjoy it,” she said,  “I miss doing other things. It really does lock you down, which was nice the first year with the babies being three, but now they’re getting more mobile, they’re about to go into school … So I just don’t know.”

Take a look.

In other JLo news, she’s just announced a tour with Enrique Inglesias and she’s made her first red carpet appearance with her new boyfriend, 25yo back-up dancer Casper.
