Ri Ri has a pyjama party with fans

Some stars won’t greet their fans without a visit from their hairdresser and make-up artist ensuring they always look picture perfect.

But for Rihanna nothing will keep away from her fans and she is ready to entertain them at any time of the day, no matter what her appearance.

The Barbadian singer, 23, was given an early morning wake-up call by fans outside her hotel in Brazil and she stepped out on to her balcony sporting huge bed hair.

In fact it seemed like Rihanna didn’t even stop to put a brush through her hair and was more than happy with her nature bouffant.

But given her flamboyant and suggestive outfits on stage fans might be a little disappointed to learn that Rihanna’s bedtime attire is conservative in comparison.

The S&M singer was dressed in her pyjamas which consisted of a plain grey vest and a pair of matching shorts.

Rihanna came out on to her balcony to wave to fans, despite her state of undress, and blow kisses to the doting crowd forming below her window.

While some might have been disappointed with her boudoir attire Rihanna did give fans a cheeky treat as she pulled up her shorts to reveal a little more of her famous derriere as she made her way back into her hotel room.

The singer, who has teamed up with Coldplay on their latest album, has announced that the next single to be released will be called We Found Love.
