Rihanna and Nicki get along well and there have even been rumours circulating the duo will move in together, something Rihanna decided to poke fun at on her Twitter page by posting a picture of the pair together in their new crib. The singer also confessed she cant stop touching curvaceous Nicki whose name she misspelt.
