Pop star caught sniffing cocaine?

Rihanna has been caught on camera sniffing on 'something' that looks like cocaine while partying with friends on a tour bus.

A short video which has since gone viral shows the singer allegedly engaging with an undisclosed substance from her table with the use of a white straw.

From the video, it seems Riri expresses shock and hurt after realizing she was being filmed by someone.

When she raises her head, a couple of friends appear in between her and the camera to shield the coverage.

As at now, there is no confirmation as to what was happening in the tour bus but nonetheless, we will keep you all posted.
