Are fans getting another Rihanna and Drake collaboration? According to multiple reports, the two superstars have reunited on a song called "Work" off RiRi's highly-anticipated album "Anti", and they are now readying its accompanying music video.

In a leaked casting call sheet that a Twitter user recently posted online, the video was shot on Friday-Saturday, January 8-9 and would include horseback riders as well as cops. Supporting the information, some other Twitter users claimed over the weekend that they spotted Drizzy, RiRi and some horses at Los Angeles' Eagle Rock Plaza.

Around the same time, Drake's seen featured in an Instagram video showing DJ Khaled announcing that something big's coming. "I'm up to something," Khaled said in the short clip, before Drake added, "Major." Currently, it's still unclear if Khaled is linked to Drake and Rih's new project.
