It's no surprise that Rihanna landed on Bing's Most Searched Celebrities this year. But how did she break into such an elite crew of celebs? All RiRi had to do was post a few salacious musings and photos on social media, make her big screen debut in "Battleship," and finally open up about Chris Brown. Let's not forget her latest publicity stunt -- holding a bunch of journalists and fans captive on a party jet (they boarded of their own will!) in honor of her 777 tour. And she's so "Unapologetic" about all of it.
