Rihanna — who appears to have ditched her red hair — chose to shock fans in a different way recently in London. She opted for the tube as her mode of transportation to the city’s famed O2 Arena, where she made a stop on her “Loud” tour on October 6.  Happily riding the British version of the subway on her way to rock out, RiRi chatted up fans and posed with them for pictures. Fan described her as “humble” and “normal” as they rode together towards a night of fun revelry in music. Head over to the UK web site for The Daily Mail for more great quotes from some of Rihanna’s freaked out fans — but stick around on Madame Noire to check out the photos of the racy star taking public transportation and entertaining on stage!
