NOBLE PRINCE An unnamed 51-year-old sister of Harry’s ex-girlfriend Cressida Bonas has died.

Prior to being told she had an inoperable brain tumor, Pandora Cooper-Key had been fighting cancer for 24 years.

Esmond Cooper-Key was a nobleman and Lady Mary Gaye Curzon was their daughter.

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

For the first time, Princess Eugenie, Sarah Ferguson’s daughter, introduced Cressida and Prince Harry in May 2012.

Harry was famously seen naked in Las Vegas, which caused some problems between them, but they dated until April 2014.

Following that, Cressida and his other ex-girlfriend Chelsy Davy attended Harry and Meghan Markle’s wedding in May 2018.

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

Later that year, the mother of two was told she had a tumor on the left side of her brain that could not be removed.

Through immunotherapy, she was hoping to get better.

Pandora, from west London, was 26 years old when she was first told she had Paget’s Disease, a rare kidney cancer.

Overcoming the illness, she had her first child about 10 years later.

Shockingly, doctors told her just weeks after giving birth that they had found a sarcoma in her left eye.

Although only a few thousand are diagnosed in the UK each year, sarcomas are very rare and aggressive tumors.

When her tear duct was removed, Cooper-Key was told she had only 10 months to live, but she fought for years.
