Rihanna knows how to rock a bikini ... and apparently a one-piece.
The "Diamonds" singer, 24, flaunted her famous figure in a bright green monokini while relaxing on the balcony of her villa in Barbados on Dec. 21. After being mobbed by fans while Christmas shopping in her hometown, RiRi stripped down for some well-deserved R&R.
Rihanna sunbathed in the low-cut -- and backless -- swimsuit as she spent time with a friend. Although it was rumored that her on-again-off-again beau Chris Brown would be accompanying her on the trip, RiRi arrived on Dec. 18 solo.
"Friday night getting a lil fuzzy," she tweeted last night, along with a photo of herself half-naked in bed.
Looks like she's enjoying her vacation...
