Rihanna vs. Kate Moss: Battle of the Sexy Gold Bikinis

Who do you think rocked the two-piece better?

It's a string-bikini showdown—isn't that the best kind?

Both supermodel Kate Moss and fiery singer Rihanna showed off their year-round, beach-ready figures—not fair—in tiny two-pieces recently, while vacationing at different destinations. 

Moss, 38, was spotted strutting a strapless, gold bathing suit, while in St. Barts with her hubby Jamie Hince, enjoying some free time after putting in work on the job (which, um, included modeling bathing suits on the beach.)

Meanwhile, 24-year-old Ri-Ri decided to head back home for some R&R.

The Barbados beauty, who rocked a barely-there gold bikini, spent time soaking in the sun and having quality girl time on the island with her BFF, Melissa Forde.
