Demi Moore offered a sincere portrait of her late friend one day after her passing. "The world has lost one of the most beautiful, kind, generous, tender-loving souls that has graced this earth," Moore wrote on Instagram. "Rest easy @therealkellypreston, we will miss you," she added along with a heartbroken emoji.

Kelly Preston & John Travolta, Demi Moore & Bruce Willis: '90s icons

The happy fivesome may have come together for the photo sometime near the late '80s or early '90s, when Willis and Travolta co-starred in three films together. Both appeared in the 1989 comedy Look Who's Talking and its 1990 sequel, as well as Quentin Tarantino's iconic 1994 crime film, Pulp Fiction. At the time, Travolta and Preston as well as Willis and Moore were among Hollywood's best-known power couples. But Willis and Moore later divorced in 2000, while Travolta and Preston remained married until her 2020 passing.
