Rihanna's Brazilian vacation seems to be heating up with each passing day.  She and her BFF Melissa Forde, have been taking loads of pictures capturing the fun memories spent together in the bikini weather, and recently uploaded a few new ones to their already broad collection.  In their new pictures, Rih and Melissa kicked back under the sun and enjoyed a few blissful moments puffing on some herb, while wearing some sexy red bikinis.  At one point, their tops came off.

Check out the Brazilian fun above.
