If Rihanna is trying to send a message to her ex Chris Brown, it's coming across loud and clear.
The pop star posed for a teasing tweet in a bikini on Saturday with the caption: 'Lil ol me in my big ol tub!!!' It's the star's second r-ácy picture this week - she also posted a chéeky shot of her derriere from the set of her Pour It Up clip on Wednesday. It doesn't seem to be any coincidence that they come after ex Chris Brown has been gallivanting about with Karrueche Tran again.
