Maggie Griffin, the mother of comedian Kathy Griffin, has died aged 99.

Her daughter shared the news on social media on Tuesday, writing: “My Mom, the one and only, Maggie Griffin, passed away today. I am gutted. My best friend. I’m shaking. I won’t ever be prepared.

“I’m so grateful you guys got to be part of her life. You knew her. You loved her. She knew it. Oh, and OF COURSE she went on St Patrick’s Day.”

The sweet, impish and quick-tongued Maggie Griffin was a frequent presence in her daughter’s reality show, Kathy Griffin: My Life on the D-List, in the early 2000s. More often than not, she was holding a glass of wine.

Griffin revealed on Twitter in January 2019 that her mother had “rapidly fallen into the throes of dementia.”

“This is never easy for any child, I know this is a reality that millions of people deal with every year,” the comedian wrote.

“But when it comes to my mom this is particularly hard because her sharp mind was everything.”

Kathy Griffin’s father and Maggie’s husband, John, died in 2007.
