Rihanna celebrated 4/20 while smoking out in a black see-through bikini that featured marijuana leaf pasties and a triangle piece covering her lower half. She celebrated the stoner holiday with her best friend Melissa, who shared several videos and photos from their day of fun.
The two were back in their home country of Barbados, where they made a trip back to the gorgeous beaches and rolled around hotboxing the back of a chauffeured SUV. Check out more photos of their wild day in the above slide.
