George Clooney mourns death of sister Ada Zeidler at 65: ‘My hero’

George Clooney announced the death of his sister Adelia “Ada” Zeidler in an emotional statement.

“My sister, Ada, was my hero,” the “Ocean’s 11” star told People on Saturday.

“She faced down cancer with courage and humor. I’ve never met anyone so brave,” he continued. “Amal and I will miss her terribly.”

The outlet confirmed Clooney’s older sibling died at age 65 Friday.

An obituary for the Augusta, Ky resident said she was born in Los Angeles in 1960 and “died peacefully surrounded by the people she loved” in a medical facility.

Survivors include her parents Nick and Nina Bruce Clooney, children, Nick Zeidler and Allison Zeidler Herolaga, husband Kenny, George and his wife Amal Clooney, and “several uncles, aunts, and cousins,” the obituary read.

She was preceded in death by husband Norman Zeidler, who died in 2004.

Zeidler was a former elementary art teacher and high school National Merit Scholar who loved reading, and she grew up alongside her brother in Augusta.

Her aunt Rosemary Clooney performed at her wedding to Norman in 1987, where George read scripture, according to People.

A memorial will be held for Zeidler on Monday.

A rep for Clooney did not immediately return Page Six’s request for comment.

Though she lived a private life, Zeidler was seen attending her little brother’s lavish Venice, Italy wedding to human rights attorney Amal in 2014.

Photos showed the proud sister sitting alongside the “Wolfs” actor, 64, in a boat amid the celebration. She wore a silver, beaded dress with sheer sleeves for the star-studded nuptials.

In a 2012 interview with the New York Daily News, Zeidler confessed that she was protective enough not to have her brother’s phone number.

“I wouldn’t want to have it in my phone and then lose my phone,” she said at the time, via the Columbus Dispatch. “He can phone me, and he does occasionally, but email is more convenient for both of us.”

George previously confirmed his tight bond with his sister. “My sister, I’m very close to,” he told “CBS This Morning” back in 2015.
