The British socialite died suddenly at the age of 45 earlier this month (Feb17). She was found dead at her South Kensington flat on 8 Feb (17). Ms Palmer-Tomkinson rose to fame in the '90s as a hard-partying "It girl".

Her death came as a shock with many speculating the former drug addict had passed away from a brain tumour. She had received treatment in 2016 for a non-malignant brain tumour, reports the BBC.

Tara's family posted a death notice to Britain's Daily Telegraph newspaper, which read: "Tara Clare died peacefully in her sleep", but her sister, British author Santa Montefiore, has now shared the socialite died of natural causes in a series of tweets.

“I’ve been so touched by the warm response to Tara’s death. Thank you from the whole family. But I'd like to clarify a couple of points,” Santa began.

“Today (15Feb) the Coroner’s report states that Tara died of natural causes – a perforated ulcer. She did not have a brain tumour.

“Contrary to some reports, Tara was not the goddaughter of HRH the Prince Of Wales," she tweeted clarifying Tara's relationship with the British royal who she knew through her father Charles Palmer-Tomkinson,

"Tara’s good friends & family know that she was in high spirits in her last days. She had plans, trips & had written a moving new song," she continued.

She finished her messages by saying a full statement from the family will follow, and thanked fans once again.

Tara had a well documented addiction to cocaine, which destroyed her septum causing her nose collapse inwards.

However she managed to conquer her demons after numerous spells in rehab, and hung up her party shoes.

In recent years Tara had turned her attention to fashion design and novel writing.
