Jay-Z almost caused a riot last night when he was spotted riding the London Tube with friends Timbaland and Chris Martin from Coldplay. The gang were on their way to the O2 Arena to perform at the latest stop on Hov’s Magna Carter world tour and allegedly had an entourage of about ten people surrounding them. Last year, Jay took the subway to one of his concerts in Brooklyn. Rihanna is also known for using the Tube to get to concerts at the O2 Arena.
