Rihanna offers sex advice to London clubbers

Rihanna surprised clubbers at a London nightclub by giving out sex advice.

The 'S&M' singer was partying at Whisky Mist in Mayfair after her concert at The 02 arena on Sunday to celebrate her brother Rorrey's 22nd birthday and after Rihanna led the revellers in a singsong, she took it upon herself to offer some wise words for the bedroom.
