It鈥檚 been quite a year for Kathy Griffin, and it looks like it will continue to be challenging. In a surprise to fans this week, the Emmy winner sported a shaved-to-the-scalp bald head in support of her sister Joyce Griffin, who is facing a new cancer diagnosis.

Griffin鈥檚 friend Yashar Ali posted two snaps of the comedian with her newly shaved head on Twitter. 鈥淚n solidarity with her sister, who is going through chemo, @kathygriffin shaved her head,鈥 Ali wrote, including a note to fans and followers to donate to the American Cancer Society. Griffin鈥檚 mom, Maggie Griffin, retweeted the pic, adding, 鈥淢y daughter Kathleen Mary is a wonderful human being.鈥

Sadly, Joyce isn鈥檛 the first of Griffin鈥檚 siblings to be affected by the disease. People points out that the star鈥檚 brother Gary passed away at age 63 in 2014 after a lengthy two-year battle with esophageal cancer. (It is unclear what type of cancer her sister has.)

In an Instagram tribute at the time, Griffin wrote, 鈥淭his AM my brave brother Gary Griffin passed away in palliative care after a brutal struggle w cancer. Our last real conversation, w my brother I loved so much, was just a few days go when I got him this signed picture from his idol, @JoeWalsh. He loved the Eagles, 70s rock, The Chicago White Sox and the Xavier 鈥榤uskies鈥欌 Oh & he was funny as sh*t.鈥

While Griffin has yet to share her own snaps of her new 鈥榙o, she did take time over the weekend to clarify to fans that she is no longer under investigation after her shocking photo shoot depicting the president earlier this year.

鈥淭ODAY. The @AP has to clarify. I am no longer under federal investigation. The case is closed, I have been completely exonerated. Finally.鈥

What do you think of Griffin鈥檚 gesture for her sister? Tell us @BritandCo!
