Rihanna is spotted leaving Stringfellows Club in London (Oct. 14, 2011)

*Rihanna allegedly angered security at Stringfellows strip club in London by ”repeatedly touching” the lap dancers — which is a strip club no-no.

The singer was at the venue on Wednesday (Oct. 12) when she reportedly couldn’t keep her hands off the topless ladies, and even put her head between one of the dancers’ legs, according to British newspaper The Sun.

“Rihanna couldn’t resist paying for a dance and loved watching the girls in action,” a source told the paper. “But the guards weren’t happy as she was repeatedly touching them, ignoring all the warnings. At one point she thrust her head between the legs of one of the dancers.”

Witnesses said the 23-year-old pop star and the baseball player partied until 2 a.m. in a private booth, where they were joined by celebrity hairdresser Adee Phelan and retired world heavyweight champion boxer (and Matt Kemp look-a-like) David Haye.

The singer is currently on tour in the UK. Earlier in the night, she Guns N’ Roses songs at the Nove Karaoke Bar in London’s West End. She went to the bar with several of her staff to celebrate a crew member’s birthday and she treated the party to beers and vodka shots and food including pizza and garlic bread.

Rihanna couldn’t stop grabbing the microphone and also performed renditions of her own tracks and Kings of Leon’s “Sex on Fire.”
