Kathy Griffin Shaves Her Head To Support Sister Fighting Cancer

Griffin’s mom called the comic a “wonderful human being.”

Kathy Griffin went bald for a beautiful reason.

The beleaguered comedian shaved off her hair in solidarity with her sister Joyce Griffin, who’s undergoing chemotherapy in her cancer battle, according to outlets.

Journalist Yashar Ali posted photos of Griffin with her new look on Monday, including one with their mother, Maggie Griffin, expressing surprise.

But it’s believed the performer actually chopped off her locks about a week ago, Entertainment Tonight reported in the segment above.

After the pics appeared on Twitter, Griffin’s mom gave the comic a shout-out as a “wonderful human being.”

According to People, Griffin lost her older brother Gary to cancer in 2014.

The recent photo shoot should have a more positive effect than the Griffin images that circulated online in May. She faced intense backlash and a Secret Service investigation in May after a photo shoot in which she held a fake bloody head of President Donald Trump.

Griffin, who apologized, tweeted on Friday that she was no longer under federal investigation.
