The diamonds singer took to twitter to reveal her latest look, grey hair.
'New color ice grey ish, call it #Brrr,' she tweeted. 'Grey is the new black! Blondies, it's quiet for y'all!'
Perhaps the star is hoping to start a new trend.
But while her Granny chic look may entertain the pop singer, she certainly isn't the first to attempt it.
Lady Gaga, Nicole Richie, Kelly Osbourne, Pixie Geldof and Kate Moss have all been there done that.
Rihanna may simply be trying to keep herself occupied amid reports that fans are tiring of her persistent lateness.
