The Rihanna featuring Drake track 'Work' just became her 14th number 1 on the Billboard Hot 100, and his second.

And that doesn't even take into account the impact of the video for 'Work,' which dropped earlier today.

Or actually it's two videos:

The first video was the one Rihanna teased this weekend. It features Rih-Rih and Drake getting down in a Jamaican dancehall.

The second video is in a less defined location. What makes it notable is Rihanna's lack of a bra.

Which visuals do you prefer?
