Demi Moore made her first official appearance since getting out of treatment, showing up Tuesday at a Beverly Hills house party to support her close friend, British TV host Amanda De Cadenet.
Hosted by InStyle Managing Editor Ariel Foxman, the intimate gathering celebrated the April 26 launch of De Cadenet’s Lifetime interview show, The Conversation. Moore is both executive producer of the show and one of its inspirations.
“The conversations that [Demi] and I have on a daily basis really reflect the questions on the show,” De Cadenet, 39, said in this week’s PEOPLE, currently on newsstands.
“She was a great sounding board. The spirit of the show is about women supporting one another so [working with her] was great.”
