Rihanna Rocks Barely-There Ensemble to Kadooment Day Parade

Rihanna was once again back in Barbados for the annual Crop Over festivities, and this time, she had a famous friend in her squad.

The 27-year-old singer was spotted partying and dancing with Nicole Scherzinger's ex-fiance, Lewis Hamilton, at the Crop Over's Kadooment Day Parade. The 30-year-old shirtless British race car driver celebrated wearing a backwards hat, trendy sunglasses and a colorful bandanna around his neck. Both his Calvin Klein underwear and his rock-hard abs were in full view.

The hat was apparently covering up his new 'do. "Barbados, we ready!! #Islandlife #Carnival2015," Hamilton captioned a selfie of his hair.

While recent pics of Rihanna and Hamilton partying are sparking romance rumors, the two known each other for a few years. In Dec. 2014, the two posed together at the British Fashion Awards in London, and in 2011, they were also photographed at the Canadian Grand Prix.

Per usual, all eyes were on Rihanna and her show-stopping costume on Monday. Like those Crop Over styles from years past, the intricately beaded getup included a barely-there bra and booty-baring bikini bottoms. Rihanna paired her sexy style with a huge headdress and giant wings.

The outlandish pop star knew she looked good because she couldn't stop Instagramming during the festivities on Monday.
