Rihanna and Lewis Hamilton have continued to send tongues wagging after being spotting partying in the Big Apple together upon their return from a sunshine break in Barbados. The rumoured couple are said to have reunited at the 1Oak nightclub in New York on 11 August.

For the outing, Chris Brown's ex-girlfriend went for a causal look of acid-wash skinny jeans and a white tank top. She completed the look with big-curly hair and pink stilettos. Her love interest wore a white top, jacket, blue jeans and Timberland boots

RiRi was first linked to 30-year-old Hamilton at the Met Gala in New York back in May, when they sat together at the after-party. Earlier in August they were spotted enjoying a day of watersports in her native Barbados. Pictures show the pair hanging out with friends on a catamaran before they took it in turns to enjoy the jet skis, inflatable boat and the rubber rings.

"They've had a flirtation for years and have always fancied each other, but since May this year they've been talking a lot. Finally their schedules allowed them to spend a weekend in the same part of the world and they made the most of it," a source added.

But even if she does have feeling for the sportsman, friends say she will not be making anything official anytime soon.

"Rihanna is dating now and she hasn't put a label on anyone," the insider added. "She is still talking to Karim [Benzema] but she is also talking to Lewis and keeping her options open. She is not at any point in her life."

Meanwhile Hamilton, who is the middle of his racing season, made sure to take time out to prepare his body.

"Morning run & gym done!! Did you train this morning? #NYC #letsgetit," Hamilton wrote yesterday.
