Rihanna, 24, made no secret of her steamy romance with Oakland Raiders star Darren McFadden on a late-April trip to Honolulu, during which she also promoted her film, Battleship.

In Touch has learned the sexy singer frolicked on a Honolulu beach in a barely there bikini on April 26. “Rihanna rushed into the ocean, but Darren had to be coaxed,” an onlooker reveals. “She kept calling his name, and at one point, she discreetly flashed him. That did the trick. He ran into the water, and they started kissing.”

While they’ve only been dating for a few weeks, the couple was spotted holding hands in the lobby of their hotel, The Kahala Hotel & Resort, dancing at a club and cuddling in a lounge chair.

But though it may look as if she’s finally over her abusive ex, Chris Brown, a pal says she’s still in love with him. “She’s using Darren to make him jealous.”

And unfortunately, it seems to be working. In Touch has learned that Chris is still in contact with Rihanna — and even sent $3,000 worth of tropical flowers to her suite!

“She was shocked,” shares the pal. And encouraged. Just days later, on May 2, she made a point of wearing a Raiders shirt to a New York strip club — and tweeted numerous pictures of herself, the pal says, in the hopes that Chris would see.
