Rihanna and Nicole Scherzinger's ex, Lewis Hamilton, continue to fuel rumors that they are dating after they were snapped yet again on another adventure while in vacation in her hometown of Barbados.

On Friday, the "FourFiveSeconds" singer and the race car driver were spotted engaging in some watersports with a group of friends on a catamaran.

"The FourFiveSeconds hitmaker wore a pretty white floral two-piece for her day on the crystal blue waters," said Daily Mail.

"Injecting a touch of glamour into the style, the singer wore a purple and turquoise bandana around her caramel colored locks and finished the look with a myriad of necklaces," it added.

Nicole Scherzinger's ex, meanwhile, wore a white tank top and board shorts for the outing.

Rihanna and Lewis Hamilton first sparked the dating rumors when they were snapped having a blast during the Kadooment Day Parade.

Wearing a huge feather headdress and wings, Rihanna participated in the annual event and she mingled with her friends at an enclosed section.

"F1 ace Hamilton was spotted hanging out near the pop princess, adding to speculation that the pair are secretly dating," said Australia's News.com. "The heavily tattooed champ, who was wearing a silver tank top with matching shorts, looked relaxed and chilled as he hung out with friends."

Lewis Hamilton split with Nicole Scherzinger earlier this year and in an interview with the Daily Mirror, he said that he's "stronger than ever."

"Of course, in the previous years it has been the case where it's affected my life in general," he explained. "Last year, I adopted, maybe the word is a mental attitude that was impenetrable but I feel that I still carry that kind of mentality from last year and whilst it's not been easy, I feel stronger than ever."

Prior to the rumor that Lewis Hamilton is dating Rihanna, he was previously linked to Kendall Jenner while the Barbadian singer was linked to soccer player Karim Benzema.
