Tara Palmer-Tomkinson has died at the age of 45.

The former socialite and reality TV star was reportedly found dead at her London home at 1.40pm on Wednesday by police.

It comes just months after the former I'm a Celebrity Get Me Out Of Here contestant revealed she had been undergone treatment for long-running battle with a brain tumour.

Police confirmed they were called by London Ambulance Service to an address South London where a woman in her 40s was pronounced dead at the scene.

It read: "Police were called by London Ambulance Service at approximately 13:40hrs on Wednesday, 8 February to an address in Bramham Gardens, SW5.

"A woman, aged in her 40s, was pronounced dead at the scene. Next of kin have been informed.

"The death is being treated as unexplained."

The socialite and reality TV star had revealed she was being treated for a non-malignant growth in her pituitary gland in November as she opened up about her battle dealing with her diagnosis.

She told the Daily Mail: "I went to the doctors to talk about my latest blood test results when I got back from skiing in January. I said: 'What does this mean? Can you translate it?' And the doctor said: 'As I suspected, you have a brain tumour'.

"I got terribly frightened. I started thinking 'I'm going to die, I'm going to die. I've only got a couple of weeks to live.' Stuff like that."

During her career in the spotlight the former newspaper columnist and later reality star spoke frankly about her personal demons including drug addiction.

In a heartfelt interview on ITV show Jeremy Kyle: The Celebrity Specials she even described her close call with death after overdosing on cocaine.

She said: "I remember timing my heart because I knew it was going to stop and I remember my telephone was (a few metres away) ... I remember crawling on my hands and knees to pick up the phone and call ... and then I woke up in hospital."

"I think that was the night I had an overdose. I have never attempted suicide ... I think it was a cry for help."

She also talked opening about her addiction and recovery while in the I'm A Celebrity camp telling fellow contestant Christine Hamilton; "The one time when I do feel it is when i'm feeling great I just want to feel a little bit greater, you know you just want to keep the high going".

Ms Palmer-Tomkinson eventually managed to quit drugs after a 35-day stint at an Arizona rehab clinic, but readmitted herself to the clinic nine years later when she thought she was having a nervous breakdown.

The former IT girl said: "I am a recluse ... I get terribly anxious going out."
