Just call her Blunder Woman.

Gal Gadot’s attempt to cheer up coronavirus isolationists with a celeb-studded cover of John Lennon’s “Imagine” backfired after Twitter users wondered why they couldn’t send money instead.

“We’re all in this together,” says the “Wonder Woman” star, 34, at the start of the viral video posted Wednesday to her 36.8 million-fan Instagram page.

The 3-minute clip then cuts to a montage of Gadot, Mark Ruffalo, Will Ferrell and other Hollywood elites singing the lyrics of the late Beatle star’s opus, which envisions a world without strife.

“Imagine there’s no heaven,” croons Gadot, seemingly wearing little or no makeup and prompting “Saturday Night Live” alum Kristen Wiig to follow with, “It’s easy if you try.”

The former Miss Israel 2004 winner says the video, reportedly recorded on day six of her own quarantine, was inspired by a clip of a trumpet player in Italy performing “Imagine” from his balcony.

But her musical morale boost rang hollow with the social media masses, who labeled the video “cringe” and “out of touch.”

“I’ve always hated this song,” scoffed one Twitter critic. “ ’Imagine no possessions’ sung by some of the wealthiest people in the world.”

“Imagine all the people … Eating all the riiiich,” snarked another.

Others wondered why the deep-pocketed diva couldn’t just send cash to help those suffering from the COVID-19 crisis, which has prompted nationwide business closures, and thousands of restaurant worker layoffs in New York City alone.

“BOO, donate if you really care abt the world rn,” wrote one Instagram financial-aid expert.

Another mocked: “Honey, look at all the rich people singing Imagine. Everything will be alright now, even though we both lost our jobs. This was so much better than money and not cringy at all.”

When it comes to lifting spirits amid sickness, Gadot’s celebrity cover doesn’t hold a candle to these impromptu Italian vocalists, who serenaded their fellow quarantiners from their balconies.
