The party never stops for Rihanna. The 25-year-old "Right Now" singer got down and dirty in the streets of Bridgetown, Barbados, on Friday, Aug. 3. Wearing a white monokini with metallic panels, Rihanna hit up the Foreday Morning Jam event, which kicked off at midnight and ended at 6 a.m. Saturday.

(One of the island's many Crop Over events, the Foreday Morning Jam is a precursor to the Grand Kadooment parade -- Barbados' version of Carnival.)

Rihanna joined thousands of scantily-clad revelers to celebrate the annual event. At one point, the pop star got down on all fours and twerked on the pavement. Rarely photographed without a drink in her hand, the single star danced with fans until a bouncer eventually gave the singer a piggyback ride home. "Woke up in paint and a veil from partying in de street all morning!!!" Rihanna later tweeted. "#Barbados #FOREDAYmorning CROP OVA almost here! #heauxm."

Miraculously, Rihanna turned up for a beachside photo shoot hours later showing no signs of fatigue or discomfort. "Glam starts NOW!!! New cover shoot today!" she tweeted. "I got a hustler spirit n-gga, PERIOD."

Wearing a knit crop top and a white maxi skirt, Rihanna showed off her taut tummy while voguing for the camera. Rihanna is currently on hiatus from her Diamonds World Tour, which resumes Sept. 13 in Macau.
