"Work work work work work"? More like WERK.
Rihanna took a break from "swagging the f**k out" during award shows and partying at the same clubs as Leonardo DiCaprio to reestablish her rightful reign as Queen of Bikinis while vacationing in Turks and Caicos. 
Exhibit A:

(And yes, the "A" there does stand for a**.)
The 28-year-old "Kiss It Better" singer showed off plenty of skin on her tropical getaway, which was well-documented on Instagram by her BFFs Melissa Forde and Jenn Rosales.

Basically, the trip looks like all booty, blunts and peak BadGirlRiRi-ness.

And those might not even be the sexiest shots from her many -- many -- impromptu photo shoots. Not when Rihanna has this L.B.B. to showcase all her best assets.

Photographer Dennis Leupold, who previously shot Rihanna for W magazine, also posted a series of photos of Rih smoking and drinking a beer while posing in the surf in Turks.

We're not sure if these shots showcasing Rihanna's new line of Dior glasses was for any official ad campaign, but if it's just Instagram product placement, it's working.

If we can look like Rihanna in those shades, we'll take a million pairs, please.
