A stunning rare portrait of late Princess Diana has recently been made public, nearly two months after new portraits of Kate Middleton were released in honour of her 40th birthday.

As per E! News, the never-before-seen portrait of the late Princess Of Wales is now on display at a new exhibition, titled “Life Through a Royal Lens,” at London’s Kensington Palace.

The simple yet elegant, monochrome image shows a then roughly 27-year-old Diana staring into the distance, wearing a satin gown paired with teardrop earrings.

As per E! News, the portrait was taken in 1988 by David Bailey who famously photographed a number of pop-cultural icons including Andy Warhol, Twiggy and The Beatles. The fashion photographer was reportedly hand-selected by Diana, who passed away in 1997 for his high-contrast lighting and minimalist style.
