The pop star left her London hotel carrying the black clutch – decorated with gold male genitalia – and amused waiting fans by pretending to poke one of her security team in the bum with it.

Sharing the joke with her Instagram followers later, she posted a snap of the goings on, writing: ‘My security getting d****** down in public by my #c**kclutch.’

‘bad gal’ Riri then posted a second picture showing the security guard laughing and added: ‘By the look on his face.....it tickled!! #c**kclutch.’

She then went on to thank the bag’s iconic designer – Vivienne Westwood.

‘Super impressive!!! Thank you to my Westwood family!! #VivienneWestwoodLondon,’ she wrote.

The British designer presumably sent the bag as a welcome gift to Rihanna, who is currently in London promoting her new Autumn/Winter collection for River Island.

On Tuesday, the singer announced her UK arrival by tweeting: 'UK Navy, I'm in London today launching the Autumn #RihannaforRiverIsland range.'

The pop star hosted a cocktail event – attended by gal-pal Cara Delevingne - at River Island's flagship store in Oxford Street, before continuing the evening at a Japanese restaurant in the capital.

Model Cara also wore pieces from the River Island collection - which will appear in stores this week.

'I literally designed everything I want to wear — exactly how I want to wear it,' Rihanna said in a promotional video.

While in the country, Rihanna also chatted to the UK’s resident ‘Chatty Man’ Alan Carr for his 100th show, which airs on Friday.
