In her sixties, Madonna, the "Queen of Pop," continues reinventing music and her ever-changing looks.

Her latest reinvention, though, which involved posing topless in a new snap, has had fans say that she is "not the same person."

She took to Instagram to share a flawless head-to-shoulder picture with her long hair flowing down to cover her bare upper body.

A silver cross and chunky chain with pendants hung down her neck, completing the minty look.

She captioned the post: "Breathwork...............#gang-gang and yea Sasha is always reliable!"

Although she attributed accomplishing this age-defying look in the shot to breathwork, her fans refused to believe that. They proposed that such transformation was more likely the result of a filter.

Others compared her to the reality TV star Kim Kardashian.

One person commented: "She doesn't even look like the same person.. way too much work done on her face."

Another wrote: "It's a filter."

A third added: "Omg, now even Madonna looks like a Kardashian."

Another chimed in: "Clearly some kind of "work" been done but not breath work lol." And one couldn't help but ask: "What happened to Madonna??

That prompted the reply: "She's unrecognizable."

A further poster said: "She's aging backward."

This would not be the first time Madonna has posted such controversial pictures.

This latest look comes just after she was criticized for posting snaps of herself in bondage-style lingerie that exposed her nipples and bum as she laid semi-seductively on a bed.

She wrote in response to Instagram pulling down the post: "I'm reposting photographs Instagram took down without warning or notification…..

"The reason they gave my management that does not handle my account was that a small portion of my nipple was exposed.

"It is still astounding to me that we live in a culture that allows every inch of a woman's body to be shown except a nipple."

The Material Girl singer continued: "As if that is the only part of a woman's anatomy that could be sexualized. The nipple that nourishes the baby!"

She reposted the pictures, covering the nipple with a love emoji.
