An X-rated video allegedly starring Rihanna has been released on the internet.

NSFW Footage After The Jump!

This newly released footage, shot in very poor light, runs for only 13 seconds and shows someone who looks a lot like Ri-Ri doing the horitzonal mambo with someone we’re expected to assume is Chris Brown.

The debate is on as to whether or not the clip is from an official Rihanna sex tape, with many pornography fanatics arguing that the star of the film is actually Lavish Styles — an adult film star with a striking resemblance to the pop singer.

The maker of the video has promised to release more footage on June 22.
