A fan at Rihanna's Diamonds World Tour concert got his money's worth and more when the singer gave a raunchy lap dance to him in Montpellier, France recently.

According to Complex, the "Stay" singer took her show to the next level by having embraced her inner sexy bad girl on May 31. She straddled a man in the steamy, sex-oozing set, which was caught on tape.

Chris Brown's ex put her crotch, which was recently on full display, in the man's face while sitting on top of him. She also grabbed his hand and pushed it against her cleavage in a really risque, jaw-dropping move.

The fan, who was identified as GJ Kooijman, was surely excited and most likely posted the hot clip on YouTube.

Apparently, Kooijman has a history of getting up close and personal with celebrities including Lady Gaga, who voted for him for Mr. Gay Netherlands, reported Complex. The dance seemed to be unexpected, but who knows if his intention was to get some "face time" with Rihanna, who has been jet setting everywhere lately.

On Wednesday, RiRi had dinner with designer Azzedine Alaia in his Belgium kitchen after visiting the late Coco Chanel's impressive apartment in Paris.

There are no signs that Rihanna is stopping to slow down or deal with her heartbreak over Brown, but maybe she is already dealing with it in her own interesting way.
