Rihanna Denies Romance Reports With Raiders' McFadden

Rihanna is adamant ... she's NOT dating Raiders running back Darren McFadden despite reports the two were spotted making out in Hawaii a couple weeks ago. Sources close to Rihanna tell us, the singer did meet Darren last month in Honolulu while she was promoting her new film "Battleship" but they kept things strictly platonic. We're told Darren who was WITH HIS GIRLFRIEND introduced himself to Rihanna as a fan ... and Rihanna bought Darren and his GF drinks on the beach. That's it.But that doesn't mean Rihanna can't support her new pal -- which might explain why the singer wore a Raiders jersey to a New York strip club last week.
