The singer, 24, posted the photo while she was backstage at the rehearsals of her upcoming world tour.

Alongside the picture Rihanna wrote: “You a real n****, then ph*** wit me! #GOLD”

Of course this is not the first time that Rihanna has shared similar pictures of herself online.

Over the past few months the ‘Stay’ singer has racked up quite the collection of inappropriate snaps.

This latest picture arrives just one a day after award winning actress and writer Lena Dunham, 26, criticised Rihanna for being a bad role model.

Lena, who won two Golden Globes this year for her critically acclaimed TV show ‘Girls’, made the comments to Alec Baldwin on his radio show ‘Here’s the Thing’.

She said: "[Fame is] an amazing thing and it's a platform that you have to take seriously.

"I used to be really into Rihanna, that popstar, and then it's like - again, I don't want to ever throw stones from my glass house - but I follow her on Instagram and I just think about how many little girls beyond what I could even comprehend are obsessed with Rihanna.

"Like, you know, she left Barbados, she's had this amazing career, she's won a Grammy... She's talented.

“And then she gets back together with Chris Brown and posts a million pictures of them smoking marijuana together on a bed. And it cracks my heart in half in a way that makes me feel like I'm 95 years old."

Jessie J previously spoke out against Rihanna’s use of social networking to promote unhealthy lifestyle choices.

She tweeted: “I’m bored... Maybe I should get naked and smoke and take pictures of myself and post them on instagram? Or NOT... *rolls eyes*”
