Rihanna is obviously cutting loose and having a lot of fun in Brazil.

Perezhilton has reported that while hanging out in Brazil, Rihanna rolls one of her favorite things in the world, a joint.

In the article, Rihanna is seen dipping in water dressed in a Charlie by Matthew Zink, one of the singer's fave swimming brands. The suit is a deep v-plunge that shows ample front with a barely there g-string that pretty much shows the entire singer's toned booty. The songstress has her faced turned upwards and with closed eyes and pursed lips, she happily smokes a joint.

The 25-year old singer has never made any efforts to hide her appreciation for marijuana and has publically admitted to being in favor of legalizing the greens.

Billboard noted before that public notice of Rihanna's relationship with marijuana started in 2010 when the singer was banned from a Barbados hotel for heavily smoking. Following this, when the singer began Instagram in 2011, she's been openly advocating for legalizing marijuana and showing how much she loves the drug.

Her penchant for marijuana has been well documented via her Instagram account where on numerous times she's posted photos of herself smoking as well as using weed paraphernalia.

Katy Perry also had a few words to say about Rihanna's marijuana use back in September. During a chat with Elle Canada, Katy had a few words to say about her friend's weed regimen.

"People say you should work out 30 minutes a day-none of us works out 30 minutes a day!" She is equally frank about why she admires her famous friends. "I think that Rihanna always looks so fresh and I'm like, 'How do you do that? We all know how much pot you smoke! And you don't sleep because you're on Instagram at four o'clock in the morning!'" she hoots with mock despair and then winks. "I'll get her secret for you."
