Lady Gaga’s fans are getting scary. On Monday a French fan grabbed her breast outside her hotel in Paris and last Thursday, she was “shaken” when a stalker got backstage at The O2 in London and was found making her way to the singer’s dressing room. A security source told British newspaper Daily Mirror: “This was a serious breach of security and the woman was heading in the direction of the stage and, more worryingly, Gaga’s dressing room. This woman had gone to great lengths to produce all the fake documentation so she could move at ease in the holding area backstage.” The obsessed fan is well known by Gaga’s security team. However, an insider added: “Gaga was understandably shaken by the incident but was a consummate professional and continued as per normal, putting on a dazzling show.”
