Rihanna and Lewis Hamilton have further fuelled dating rumours with a night out in New York City.

The 'Diamonds' hitmaker and Formula One racing supremo arrived within minutes of each other last night (14.08.15) at The Griffin nightclub, according to the New York Daily News.

Rihanna, 27, was spotted getting cosy with Lewis, 30, at the annual Crop Over carnival in Barbados recently, and the pair spent some quality time together.

A source told E! News at the time: ''Rihanna and Lewis had a nice little getaway last weekend in Barbados.

''Rihanna also spent time with her friends and family but Lewis was the only romantic interest on her mind.''

''She is taking it very slow and just having fun, but she likes who he is and what he is about. There's no label on them just yet.''

Rihanna was recently linked to actor Leonardo DiCaprio while Lewis enjoyed a long-term on/off relationship with pop babe Nicole Scherzinger.

The 'B**** Better Have My Money' singer recently added reality TV coach to her growing list of career moves, after signing up as a mentor for the new series of The Voice US.
