Rihanna leaves little to the imagination in one of her skimpiest outfits yet - a swimming costume she has been showing off on Twitter.
The outfit - which looks set to produce some unusual tan-lines - was accompanied by the caption "Wake... bake... #CAKE" on the social networking site.
The star was seen struggling to handle the precariously-cut outfit whilst lounging on a boat with pals in Hawaii. Thank goodness she didn't attempt to swim in it...
The 'We Found Love' singer has courted plenty of attention while she holidays on the popular island. She was photographed smoking a suspicious-looking cigarette earlier this week, suggesting on Twitter later that it was "kush", a type of cannabis.
Her Armani advert has also emerged, showing her wearing unsurprisingly few clothes.
