Elton John honors friend Princess Diana on the 20th anniversary of her death

Today, Aug. 31, marks 20 years since we lost Princess Diana in a devastating car wreck in Paris, and one of her famous friends took to Instagram to honor her on the somber anniversary.

Elton John, who was pals with Diana and famously performed at her funeral six days after she passed, shared a heartwarming photo of the pair together on Thursday.

The smile-filled photo shows Elton and Diana posing next to each other -- both in all black with intricate detailing, with Elton opting to add an ornate blue vest -- in front of a wood wall. The photo appears to have been taken sometime in the '90s, judging by their appearances.

"20 years ago today, the world lost an angel," he captioned the sweet photo. "#RIP"

Elton John's tribute is surely the first of many to come from Diana's famous friends.
