'Sound of Music' child star details Melania Trump's role in White House Christmas decorating

Turner said she helped decorate the White House for Christmas in 2017 after leaving Hollywood to become a florist not long after "The Sound of Music" first debuted.

"Melania is actually the one who works with the lead person to put the White House together," Turner said.

Turner described the experience as one of the most "physically grueling and cool things" she has ever done.

"It was a week-long deal. It was me and 149 other designers that they put to task to do all these things to make the magic of Christmas at the White House happen," Turner said.

"The most proud moment of that house was doing the largest tree, which is in the Blue Room," said Turner.

"I got to decorate the People's Tree, which was kind of the centerpiece or the focal piece of the entire White House," she added.

While she described the opportunity as "pretty amazing," Turner also recalled a frightening moment.

"I had to go up on scaffolding. I almost fell and killed myself," she added.

Turner told People she is nearing retirement but said she would return to help decorate the White House again if given the opportunity.
