Rihanna surprised passengers travelling on the Jubilee underground line last night after she caught the tube to her OWN concert at London's O2 Arena.
According to The Sun, the What's My Name superstar even used an Oyster Card to make the journey to North Greenwich station, leaving fans shocked to see her on public transport.
While on the tube, RiRi posed for pictures with her Navy, with one lucky fan posting an image of herself and the 23-year old on Twitter.
A source told the newspaper: "Fans couldn't believe they were sharing a carriage with a world famous pop star."
They added: "She was just like any other passenger, except accompanied by a huge entourage. She was happy to pose for snaps and talk about the gig. She was so down to earth"
After her underground journey, it is thought the Bajan babe left the station and hopped into a waiting car - which drove her the short distance of 100 yards to the backstage area of the O2.
The We Found Love singer, who recently announced her new album will be called Talk That Talk, went on to put on an impressive first show at the London venue, tweeting: "I been waitin 4 this all year."
