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

Kathy, an outspoken LGBT+ rights activist, confirmed on Instagram that she was “gutted” that her “best friend” passed away only “hours ago”.

Sharing a serene snap of the pair sipping drinks by an infinity pool in Los Angeles, looking over the green woodland ahead, Kathy paid tribute to the fan-beloved wine-swigging presence in the comic’s 2005-2010 reality show, Kathy Griffin: My Life on the D-List.

Kathy Griffin: ‘I am not doing well in this.’

“My mom, the one and only, Maggie Griffin, passed away today,” Kathy wrote.

“Hours ago. 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.

“Her point of view. So unique. We just GOT each other.

I’m so grateful you got to be part of her life. You loved her. I know it. She knew it.

“She’s irreplaceable.

“I’m telling you right now, I am not doing well with this. I’m rambling now. Sorry. It truly feels like the end of an era.

“Oh, and OF COURSE she went on St Patrick’s Day.”

Maggie would have celebrated her 100th birthday on June 10.

As the comment section of the post was flooded with heart emojis, celebrities rolled out touching condolence messages, including Chrissy Teigen, Sharon Stone and Kris Jenner.

“God Bless precious Maggie and may she Rest In Peace, love you, Kathy,” Jenner wrote on Instagram.

Maggie Griffin had dementia. 

Back in January 2019, Griffin revealed that her mom was deep in the throes of dementia.

“This is never easy for any child,” she said at the time.

“I know this is a reality that millions of people deal with every year. But when it comes to my mom this is particularly hard because her sharp mind was everything.”

Maggie’s IMDb profile spanned countless projects that supported her daughter’s comedic career.

Alongside My Life on the D-List, Maggie appeared on the short-lived MTV series Kathy’s So-Called Reality, as well as her eponymous Bravo talk show.

Her last on-screen credit was on the 2019 documentary Kathy Griffin: A Hell of a Story.
