Last night, InStyle celebrated Lifetime’s new interview series The Conversation with Amanda de Cadenet with the ladies behind the powerful new series—executive producer Demi Moore (in Lanvin) and renowned photographer and host of the show Amanda de Cadenet (in Roland Mouret). “My show is really about celebrating women,” de Cadenet told us at the soiree, which was held at author Jane Buckingham’s Beverly Hills home. And her best friend Moore was there every step of the way. “I’ve seen them all,” Moore told her party pals—which included Nicole Richie, Michelle Tractenberg and Rachel Zoe—of the soon-to-air episodes. “It was me in the editing room on my iPad.” Conversation, which marks de Cadenet’s U.S. TV debut, premieres April 26th on Lifetime.
