Lady Gaga was left shaken after a stalker managed to get backstage at her 02 arena gig last night using forged passes.
The woman, who is said to be known to Gaga and her entourage, was found heading towards the singer’s dressing room with forged backstage passes and laminates.
After being detained by security guards she was questioned by police and eventually released.
A source told The Daily Mirror: “This was a serious breach of security.
“The woman had gone to great lengths to produce all the fake documentation so she could move at ease in the holding area backstage.”
Her spokesperson refused to comment on the incident but another insider said: “Gaga was understandably shaken but was a consummate professional and continued as per normal, putting on a dazzling show.”
The incident is the second security breach to hit Gaga’s latest tour. On Monday a fan allegedly grabbed her breast outside a hotel in Paris before being dragged away by her security guards.
