They recently sparked dating rumours when they were seen cosying up at the Kadooment Day event in Barbados on Sunday.

And Rihanna and Lewis Hamilton did nothing to hinder the speculation as the pair were spotted partaking in watersports together as they continued to enjoy life on the sun-soaked Caribbean island on Friday.

Joined by a group of friends, the duo looked to be having the time of their lives as they surfed the waves on a catamaran, though opted against sharing the same inflatable.

Instead Rihanna who was clad in a bright pink life jacket, rode a vessel with three of her girlfriends, and Lewis a separate one with a male companion.

It looked as though the ride eventually got a little too bumpy for the American Oxygen songstress though, as she and her pals were eventually seen cascading into the water as their inflatable flipped into the air.

Swimming toward the attached speedboat, the singer removed her life jacket and revealed the skimpy swimsuit she donned beneath.

Lewis, who’s more than used to travelling at speed, seemed to enjoy his time on the jet as he took some time out from Rihanna and her girl pals on the boat.
