Talk about a string bikini!

Rihanna showed off her super-toned body in a barely-there suit on Thursday while hanging out on the beach with family and friends in Barbados.

The singer, who recently participated in the Kadoomant Day Parade in her home country, was spotted riding on a WaveRunner, boating and gliding across the choppy waters on an oversized tube, with her brunette (again) hair blowing in the wind.

Soon, though, it’s back to work: Rihanna’s Loud Tour plays Barbados on Friday.
