Rihanna showed off her naughty sense of humour as she flashed her raunchy new penis-decorated handbag in London on Wednesday (11Sep13).

The Rude Boy hitmaker was clearly in a playful mood as she stepped out with her Vivienne Westwood clutch, which was emblazoned with a giant gold phallus, and greeted the crowd gathered outside her hotel.

Rihanna gave fans a show as she stuck out her tongue and held the accessory next to her crotch before chasing after her security guards with it.

The singer later posted photos of her antics on her Twitter.com page and tweeted, "My security getting d**ked down in public by my c**k clutch... By the look on his face... it tickled!!"
