Rihanna Snorting Coke? [VIDEO]: Chris Brown's Ex Parties Hard at Barbados' Crop Over Festival 2013, Spotted Sniffing Mysterious Substance, Hardcore Drugs/Cocaine?

Rihanna's currently in her native Barbados celebrating the annual Crop Over Festival - and the "Diamonds" songstress appears to be partying VERY hard! First, Chris Brown's ex was spotted getting crunk in the club in a sexy white bodysuit... she even hit the dance floor in a freaky "twerk" breakdown. Now, a shady video recently went viral on Youtube, where RiRi appears to be snorting a mysterious substance... perhaps Cocaine? Has the Barbadian beauty's wild-and-crazy ways gotten a little too out-of-control?

Check out the seedy "sniffing" clip entitled "Rihanna Allegedly Caught Doing Coke?"

As one Youtuber sums it up...

papermyles: "she freely admits to smoking weed , every once in a while something a lil stronger tends to be in order . not a surprise this is what she she choses to do..."

Some fans don't care... it's nobody's busniess what RiRi decides to put in her body. Still, others claim that's definitely not her snorting Coke... there's no way.

What do Mstars readers think? Is there reason to be worried about the "Stay" songstress, or can she handle herself just fine?
