Tulisa was left shaken after she was confronted by a stalker in the middle of the night at her £5 million mansion home.
The 24-year-old man sneaked past the security measures at the star’s gate and started banging on the front door demanding to speak to the singer, the Irish Sun reports.
Tulisa hid in her home as the screaming man banged on her door.
She sent her PA, Gareth Varey, to answer the door before there was a heated argument.
The man fled from the gated home after police were called but they tracked him down and arrested him.
It transpired that the stalker had called to Tulisa’s home after spending the day posting notes to her.

Tulisa has had a rough few weeks of it.
A source close to the singer said: “She has had an absolutely hellish past few days, and now this.
“She is at an all-time low. This is a girl whose professional life is in tatters. This guy started hounding her daily since the drug fixing story broke.
“He started knocking down her front door in the middle of the night and Tulisa was utterly petrified.
“This is the last thing she needs to be dealing with right now.”
Tulisa is only just recovering from last week’s drama when the 24-year-old was arrested on suspicion of supplying cocaine.
The police reported after the arrest: “The man was served a first warning for harassment. He was released with no further action and all parties involved are satisfied with this.”
