Several of the \"Suddenly Susan\" star's famous friends, such as Kris Jenner and Carson Kressley, left sweet birthday wishes for Maggie.
The elder Griffin became a fan favorite on her daughter's Bravo reality show, \"Kathy Griffin: My Life on the D-List,\" for her snarky humor and ultra-endearing, down-to-earth personality.
On March 17, Kathy broke the devastating news that her mother passed away.
\"I am gutted. She was my best friend. She was my family. You knew her. She appreciated you guys so much. I'm shaking. I won't ever be prepared,\" she wrote at the time. \"I'm so grateful you got to be part of her life. You loved her. I know it. She knew it. She's irreplaceable.\"
