Rihanna Heats Up Hawaii In Sting Bikini [Photo]

Rihanna makes Hawaii 10 times hotter this week while enjoying some free time. The 23-year-old We Found Love hitmaker wore a black g-string bikini while relaxing in the water on a surfboard.

Earlier this week, the Bajan pop beauty was spotted on the beach smoking what appears to be marijuana. She has been rumored to be secretly dating ex-boyfriend Chris Brown.

The two are scheduled to see each other publicly for the first time at next month’s Grammy Awards.
