Eighties pop star Deborah Gibson called the police on an alleged stalker because a past fan scare taught her you can never be too careful when it comes to obsessed devotees.

The Shake Your Love singer has filed a restraining order against Spaniard Bassas Jorge Puigdollers after he showed up at her house on Sunday.

Gibson reveals the scary incident was the latest in a long line of encounters with Puigdollers, who she alleges has continually shown up at her home and hotel rooms when she’s on the road.

Speaking out about Sunday’s incident, the singer tells People.com Puigdollers knocked on her door and then left a note for Gibson when she refused to answer.

She says, "That was crossing a line, so that was really scary. I am a single female, so I reacted like anyone would and called 911." Police detained Puigdollers, but did not charge him with any crime.

The Spaniard’s actions have brought a host of bad memories back for Gibson she was named on murderer Robert Bardo’s fan list.

Stalker Bardo shot actress Rebecca Schaeffer at her Los Angeles home, when she opened the door to him in 1989.

Gibson recalls, "I was very young at the time, but it was scary, because I realised that whether you live or die can come down to security. This woman (Schaeffer) answered her door and was killed. From then, I’ve always had good security."
