Word is Rihanna and N.E.R.D front man Pharrell Williams have been spending quite a lot of time together, including late night rendezvous’ at hotels. Apparently, these two have gotten really close since Pharrell started working on RiRi’s new album last month. A snitch tells U.K.’s Daily Mirror,

“It’s no secret that Rihanna and Pharrell have chemistry. Adding, “And not just in the studio - they seem mesmerized by each other. But Chris will be gutted to learn he could have lost Rihanna to one of the sexiest men in music. Rihanna and Pharrell talk on the phone all the time and whenever she can get a break in her schedule she’ll go and support him at a gig.”
