Rihanna is hip-hop. She's also a pop star/entrepreneur/actress/hottie/celebrity, but don't get it twisted—Rihanna is most definitely hip-hop. She floats over a Mike Will Made It beat as well as any rapper. Her Twitter and Instagram feeds are littered with rap lyrics relevant to her life because, quite frankly: SHE LIVES THIS SHIT. She's BFFs with Jay-Z and Kanye West. She had Drake throwing bottles at her R&B ex-boyfriend. And, she's made awesome songs with all three of those guys, and a lot more folks who work in the genre. Rihanna is so important to the rap game that it's not even funny. Check out this list of her 10 Best Hip-Hop Collaborations and try to say otherwise.
