Vidya Balan, who has become a sex siren post her bold avatar in The Dirty Picture, has certainly doubled her fan base. So much so that the admiration has turned into obsession for one of her fans. A man in his late 20s used to follow Vidya to her film sets and eventually, he reached her apartment as well.

"He used to be there on her sets. He used to be there in her building. Once unknowingly, Vidya even nodded to him and said namaste," a friend of Balan told Mumbai Mirror. "He was obsessed with Vidya," a resident of the same apartment as Vidya told the tabloid.

However, things got out of hands last week. "The stalker managed to go up to Vidya's flat. Thankfully, Vidya was not at home at that time. Her sister, who delivered twins in November last year, opened the door. When told that Vidya had gone out, the stalker asked if Vidya had gone out with her niece Ira and nephew Ruhaan," the tabloid quoted the friend as saying.

The Dirty Picture star got suspicious and asked the security guards to keep a watch on the stalker. When the stalker returned, security guard called the cops. However, the cops left him after a warning. Katrina Kaif and Kangna Ranaut have also been stalked earlier.
