Rihanna Lap Dance [VIDEO]: Chris Brown's Ex Treats Lucky Fan to Erotic Solo Performance During 'Diamonds World Tour' Gig in France

Rihanna is single and ready to mingle... and one lucky fan received a sexy gift from RiRi during a recent Diamonds World Tour performance in France. During her "Diamonds" gig on Sunday (June 2), Chris Brown's wild ex pulled a guy up onstage and treated him to an erotic lap dance! Flaunting a kinky, skintight corset, Rihanna's raunchy solo performance really stole the show! Check out the racy concert clip below.

In the middle of her sultry performance in Montpellier, France, RiRi turned to the audience and asked, "Alright I need some help on this part... Any fellas wanna help me out... how about my ladies?" That's when she pulls a young stud up onstage, straddles him, and beings grinding:

At one point, RiRi grabs the fans hand and trails it down her own body. Sexy, or sorta inappropriate?

We're betting that the lucky dude considers the lap dance experience one of the highlights of his life.

Rihanna's known for her wild, sexy antics... remember this 2011 Miami lap dance with a female fan?
