Yet she’s come under fire for a recent social media post during a trip to Greenland that many are branding “tone-deaf”.

The 82-year-old was widely praised earlier this year after posing for the

Sports Illustrated Swimsuit issue in May, but her most recent Instagram offering

has failed to inspire the same sort of positivity.

On Tuesday, August 29, Stewart uploaded a photo of herself from a cruise that

saw her take in the east coast of Greenland. The picture – one of several – shows the businesswoman

and TV personality enjoying a cocktail, along with the caption:

“End of the first zodiac cruise from @swanhelleniccruises into a very beautiful fjord on the east coast

of greenland. We actually captured a small iceberg for our cocktails tonight.”

Harmless though Stewart almost certainly intended her post to be,

it soon evoked the ire of followers who believed her using of the “small iceberg” for her drink was in bad taste.

Before long, Stewart’s comments field was filled with people hitting out at the fact that she’d referenced a small iceberg when the “ice caps are melting”.

“Martha the ice caps are melting don’t put them in your drink,” one Instagram user wrote.

Another added: “I generally love Martha and the excesses of her life because he’s about beautiful gardens, homes, and food, but wealthy white people drinking their iceberg cocktails while the planet is in flames is a bit tone deaf.“

“So as the climate warms due to the profits of a couple thousand people, billionaires vacation to the melting icebergs, scoop them up and use them to keep their cocktails cold. That sounds like a line from a dystopian novel. Can’t make this shit up lol,” a third quipped.

“Global warming and melting ice caps but we need glacier ice for cocktails?! Talk about tone def. Been a fan for years but I’ve seen enough caviar lately as I struggle to buy groceries that I’m out,” said a fourth.

Back in May, Stewart made history as she confidently posed in daring swimsuits for cover of Sports Illustrated. The then-81-year-old also spilled the rigorous wellness routine she implemented beforehand.

“I didn’t starve myself, but I didn’t eat any bread or pasta for a couple of months,” Stewart mentioned during an appearance on the Today show.

“I went to Pilates every other day, and that was great; I’m still going to Pilates every other day ’cause it’s so great. And I just, I live a clean life anyway – good diet and good exercise and healthy skincare and all of that stuff.”

During her keynote speech at the Las Vegas event, Stewart shared how fans responded to the “authentic” cover.

“The response to it was really encouraging because it made women of all ages feel like, ‘If she can do it, then I can do it too,’” Stewart noted.
