Rihanna blasts fan on Instagram over Whitney Houston comment

So Rihanna posted a photo of herself smoking a joint (photo you see on the left) on her instagram page a few days back and a fan put a comment there saying RiRi would end up like Whitney Houston. Rihanna, who's notorious for checking fans who try her on social media, put the smack down on the fan immediately. Below the photo on the right is what the fan said to her and under it is Rihanna's reply.
