Success. In her career, Pink has released five platinum albums, won two Grammys and sold over 30 million albums globally. Her net worth hasn't been published, but considering the royalties she receives from her songs on TV and in movies (along with albums sales and tours), she's probably raking in a bundle. Hart earns his paycheck from ad campaigns and cameo appearances -- and let's not forget his stint on the fifth season of The Surreal Life. We wonder if it's awkward that she's made a living writing break-up songs that bash him?
Attractiveness. Pink's signature look is rebellious and occasionally androgynous, so it's hard to classify her as beautiful. Still, her body's rockin'. As for Hart: He could do without the soul patch.
Popularity. Last month, around 30 million people searched Google for Pink, vastly more than any other celeb on our list. Of course, there's a disambiguation issue to note, because not everyone who searches "pink" on Google is looking for the singer. Still, she gets props for choosing such a buzz-worthy stage name. Hart performed far worse, though not terrible, with around 60,000 searches.
Staying Power. This couple tied the knot in 2006 after dating for a few years. They announced their separation in 2008, but Hart recently confirmed that they're "dating" again. It's not the most conventional path, but since when did a Hollywood romance follow one of those?
Compatibility. The stars have spoken, and this relationship is a go. Pink's a needy Virgo and Hart is a passionate Cancer, so he's able to provide all of the security she craves. Not that she cares or anything: She's a rock star.
