George Clooney is mourning the loss of one of his closest confidants.
Adelia “Ada” Zeidler, 65, died Dec. 19 after battling cancer, Clooney confirmed to People.

“My sister, Ada, was my hero,” Clooney said Dec. 20. “She faced down cancer with courage and humor. I’ve never met anyone so brave.”
“Amal and I will miss her terribly.”
According to Zeidler’s obituary, she died peacefully surrounded by the people she loved in Edgewood, Ky. A funeral mass is set to take place Dec. 22.
A talented artist, she shared her skills as an elementary art teacher at Augusta Independent School for several years. In high school, her academic achievements qualified her to be a National Merit Scholar.
Born in Los Angeles on May 2, 1960, Zeidler-who resided in Augusta, Ky.-was active in her community, taking part in a local book club and serving as a member of the Augusta Art Guild.
She also previously held the title of grand marshal of Augusta’s Annual White Christmas Parade, per the obituary.
While Zeidler largely stayed out of the public eye, she maintained a close bond with Clooney through the years.
“I wouldn’t want to have it in my phone and then lose my phone,” she told The Columbus Dispatch in November 2012. “He can phone me, and he does occasionally, but email is more convenient for both of us.”
Predeceased by her husband Norman Zeidler in 2004, Zeidler is survived by her and Clooney’s parents, Nick Clooney and Nina Clooney, as well as her children Nick Zeidler and Allison Zeidler Herolaga.
