(CNN) Celebrities have taken to social media to pay tribute to Gloria Vanderbilt and share their respects with her family.

Vanderbilt died on Monday at the age of 95, according to her son, CNN's Anderson Cooper . Vanderbilt was an iconic fashion designer, socialite and artist.

Bravo TV's Andy Cohen is a longtime friend of Cooper. Cohen took a moment at the end of his Monday show to remember Vanderbilt.

"Gloria Vanderbilt was an amazing woman who lived a life filled with incredible peaks and impossible obstacles," Cohen wrote on Instagram. "Through it all she remained eternally optimistic with a wicked sense of humor."

Comedian Kathy Griffin has been a longtime friend of the family. She was formerly a co-host of CNN's annual New Year's Eve program with Cooper. In a tweet on Monday, Griffin shared she was flattered when Vanderbilt referred to her as her own daughter.

1) I lost a friend today. The one and only Gloria Vanderbilt. I loved her so much. She let me call her "Glo Vandi" and I would be so flattered when she would refer to me as her daughter. When we would have our alone time, we would sit on this sofa and talk for hours. pic.twitter.com/GeziwAyh4f — Kathy Griffin (@kathygriffin) June 17, 2019
