Tulisa Contostavlos was allegedly confronted by a screaming intruder at her home in the early hours on Tuesday (June 11).
A man, 24, is said to have got past security equipment at her home before banging on the front door and demanding to see her, according to the Daily Mail.
Insiders claim that Tulisa sent her PA Gareth Varey to answer the door, who then had a "heated altercation" with the fan.
The intruder then fled the home before police managed to track him down and make an arrest.
Tulisa's latest incident comes after a tough few days for the former X Factor judge, after being arrested on suspicion of supplying cocaine last week. She is also said to have been tricked into starring in a fake movie, according to tabloid reports.
The man reportedly pushed notes through Tulisa's letterbox before ringing the doorbell and shouting her name.
Hertfordshire police confirmed they had arrested a 24–year-old man from Stamford Hill in North London on Wednesday.
They stated: "The man was served a first warning for harassment. He was released with no further action and all parties involved are satisfied with this." (source)
At this point it literally isn't even funny how much **** is happening to her all at once.
Poor girl, everything is happening to her at the same time
I can't believe she kept Gareth as her PA. Fazer & Dappy did not LIKE him. He was a mess by giving her all the magazine covers and media attention during the NDUBZ time.
