“The family requests that you respect their privacy during this time of sorrow,” Susan Magrino said in a statement.

A cause of death was not provided. The New York Post reported Christiansen died at his home of a suspected heart attack after feeling sick.

Christiansen, a contractor who lived on a ranch in Fairfield, Connecticut, once appeared in a cooking segment with his sister to help make a blueberry pie with berries grown in his yard.

Stewart noted that George was born on George Washington’s birthday and had “an affinity for pie making.”

In addition to Stewart, Christiansen is survived by his wife, Margaret "Rita" Christiansen, and their children, Kirk and Kristina.

Stewart, 75, has four other siblings. In 2014, she lost a sister, Laura Kostyra Plimpton, to a brain aneurysm.
