The sister of Harry’s ex-girlfriend Cressida Bonas has died.

She was 51 years old.

Pandora Cooper-Key had been fighting cancer for 24 years before she was told she had a brain tumor that could not be removed.

Mrs. Esmond Cooper-Key and Lady Mary Gaye Curzon had a daughter named Cooper-Key.

She had ten siblings and was half-sister to actress and model Bonas.

The daughter of Sarah Ferguson, Princess Eugenie, set up the meeting between Cressida and Prince Harry in May 2012.

Before they broke up in April 2014, they had a rough patch after Harry was famously caught naked in Las Vegas.

After that, Cressida and his other ex-girlfriend Chelsy Davy went to the wedding of Harry and Meghan Markle in May 2018.

Cooper-Key, a ceramicist who used to work for Vivienne Westwood as an accessories designer, said that her family had planned her funeral “thousands of times.”

The mother of two was told at the end of last year that she had a tumor on the left side of her brain that could not be removed.

She had been getting immunotherapy in the hopes of getting better.

Pandora first learned she had Paget’s Disease, a rare cancer of the milk duct, when she was 26 years old and lived in west London.

After about 10 years, she had her first child. She was able to beat the disease.

It was terrible to hear that doctors had found a sarcoma in her left eye, just a few weeks after giving birth.

Sarcomas are very rare tumors; only a few thousand are found each year in the UK. They are very aggressive.
