Princess Diana and Liza Minnelli at the Ritz in 1991.
The two met at a party after a film premiere. Diana was apparently scolded for going to an after party but she didn’t regret it. She and Liza talked all night bonding over their humor and the difficulties in their lives.
Liza said whenever she felt down she thought of Diana and it helped her endure her troubles. Though it was long distance, the two kept a friendship until Diana’s untimely death in 1997.
