The 23-year-old pop singer turned up at the famous Stringfellows club in London with ex-boyfriend Matt Kemp, 27, and a number of others.
It's claimed she got in trouble when she couldn't keep her hands off the dancers and put her head between one of the dancer's legs.
A source said to UK newspaper The Sun: 'Rihanna couldn't resist paying for a dance and loved watching the girls in action. Bouncers weren't happy as she was repeatedly touching them, ignoring all warnings.
'At one point she thrust her head between the legs of one of the dancers.'
