Princess Diana's photo from Luciano Pavarotti's free concert in London's Hyde Park, Great Britain, in 1991 once again surfaced. The Princess of Wales looked incredibly beautiful even if she was soaking wet after leading the concertgoers to put down their umbrellas amidst the heavy rain.

The downpour could have been a disaster for the charity concert, but it turned out to be a huge success. The show's promoter, Harvey Goldsmith, urged the viewers to put their umbrellas down so that they wouldn't obstruct the view. From here, something incredible happened.

Princess Diana, who was in the VIP area with her then-husband, Prince Charles, was one of the first to take her umbrella down. Her move then rippled, followed by the rest of the audience. Dickon Stainer, Universal Music Group Classics and Jazz president, who was still a young classical music executive at the time, witnessed the hair-raising event, playing out on the giant screen.

Princess Diana didn't mind getting soaking wet, following the promoter's order. "It played right to her 'People's Princess' image, Diana not bothered about the buckets of rain," Stainer said, via USA Today.

In an unearthed photo on Instagram, Princess Diana still looked incredibly gorgeous even if she was wet all over. The snap showed Princes William and Harry's mother not minding being soaked in the water while talking to Luciano Pavarotti.

At one point, the operatic tenor kissed Princess Diana on her hand. She was also all smiles when they talked.

Fans once again praised Prince Charles' former wife for what she did and her looks. Despite having scruffy wet hair, dripping wet clothes, and seemed to be chilling, fans said she was still a "naturally gorgeous woman." "Her beauty is beyond! Takes my breath away each & every time," another Instagram user commented.

In Ron Howard's documentary, Pavarotti, it showed the fairy-tale-like, enchanting scene of Luciano Pavarotti serenading the rain-drenched Princess Diana. It was said to be the most "romantic high-water mark" for one of the most commercially successful tenors of all time. Since then, a new friendship began.

Stainer recalled that it was Luciano Pavarotti who met Princess Diana in the rain. The romantic image of the great singer addressing the princess went down in history as one of the most iconic moments in popular culture.

Luciano Pavarotti then dedicated "Donna Non-Vidi Mai," which meant "I Have Never Seen a Woman Like That" in English, to Princess Diana. Although he asked Prince Charles' permission to sing the song, it looked like nothing could stop him at the time.
