The 'We Found Love' hitmaker was photographed outside the Rose nightclub in central London sporting a pair of thigh-high black-and-white boots apparently made from reptile hide, reported Daily Express.
But her fashion choice has angered officials at People for the Ethical Treatment of Animals (PETA), who have spoken out to brand Rihanna's footwear "callous".
"Rihanna may not have a clue that snakes killed for boots are often nailed to a tree and skinned alive. Of course, they can't go on Oprah to cry about it.
"Wearing reptile skin is creepy and callous, and it makes her look even more out of touch. She and Lady Gaga seem so desperate to be freaks instead of recognised for their talents that you have to wonder if they realise that they are being laughed at," a PETA spokesman said.
