The 'We Found Love' singer was spotted joking around on the show's former set.
Rihanna took a break from filming her new video4, 'You Da One' to play around on the old set of Dragon's Den.
The Bajan star apparently had the crew in hysterics as she started doing her best impressions of the show's famous business investors.
The video shoot was taking place in London's Stoke Newington where crew members assembled an array of chairs in the same style as seen on the TV series.
A source said: "Rihanna was happy to play along. She was prompted to say things like, 'I'm Out' and, 'I'll offer you 20 per cent of the business'."
