Rihanna allegedly got into trouble with security guards of a strip club called Stringfellows in London.

She was in town for a visit with her ex-boyfriend Matt Kempt. According to sources, Riri couldn't keep her hands off topless dancers, even putting her head in between a male dancer's legs.

"Rihanna couldn't resist paying for a dance and loved watching the girls in action. But the guards weren't happy as she was repeatedly touching them, ignoring all the warnings," a source tells The Sun.

"At one point she thrust her head between the legs of one of the dancers."

The famous popstar and the baseball player partied in the club up until 2 am. They were together with celebrity hairdresser Adee Phelan and retired world champion boxer David Haye in a private booth.

Rihanna went into the bar to celebrate one of her member's birthday. The sexy singer treated beer, vodka shots, and food for her crew members that night. Reports say that she couldn't stop grabbing the microphone and performed some of her songs and also a rendition of Kings of Leon's "Sex on Fire".
