Move over, Lady Gaga -- there's a new queen in town. Actress, singer and (possibly soon-to-be former) 'American Idol' judge Jennifer Lopez bested Mother Monster and a slew of other high-powered stars to take the top spot on this year's Forbes Celebrity 100 List.

The Forbes celebrity rankings aren't all about how much money someone makes, though the $52 million J. Lo brought in last year would make her rich by anyone's standards -- the list also takes into account overall fame and internet notoriety, things Lopez also has in spades.

Topping the list is an especially impressive feat for Lopez, whose once-hot career was on life-support before she joined 'Idol' in 2010. Since then, she's used the show as a publicity platform, landing pricey endorsement deals with companies like L’Oreal and Gillette along the way. Her 6.6 million Twitter followers and 12 million Facebook fans are also evidence of her soaring social media popularity.

Oprah Winfrey took the No. 2 slot on the Forbes list, and even though she's had a rough year trying to keep her struggling namesake television network afloat, earning $165 million means she won't be eating Ramen noodles anytime soon. Tween phenom Justin Bieber came in third, followed by singer Rihanna in fourth, and Lady Gaga, who dropped from first in 2011 to fifth this year.

Rounding out the top 10? Newly-minted 'X Factor' judge Britney Spears, professional camera-hog Kim Kardashian, pop star Katy Perry, 'Rock of Ages' actor Tom Cruise, and mega-director Steven Spielberg.
