Taylor Swift fans were left stunned after a photo of the singer looking very different went viral on Thursday.

In the image, the Love Story hitmaker, 33, posed on a red carpet as her cleavage almost spilled out of a black dress.

But many of Taylor’s fans quickly pointed out that wasn’t the popstar’s physique and her face had been Photoshopped on Kate Upton’s body.

‘Is her head Photoshopped because those aren’t hers,’ one person commented.

‘That’s actually an AI using her face and an actress’ body but it’s a good one,’ another one said.

‘There is absolutely no way that’s Taylor Swift’s body,’ a third commented.

Another joked: ‘Where has she been hiding those?’ while one said: ‘Um when did this happen?’

‘This is just her face pasted onto someone else’s body,’ another reassured.

Meanwhile, Taylor took to social media on Wednesday to thank her legions of fans for supporting her new concert film.

The pop superstar also revealed on Instagram that she was releasing live audio of Cruel Summer from The Eras Tour.

‘What a truly mind blowing thing you’ve turned The Eras Tour Concert Film into. I’ve been watching videos of you guys in the theaters dancing and prancing and recreating choreography, creating inside jokes, casting spells, getting engaged, and just generally creating the exact type of joyful chaos we’re known for,’ Taylor posted.

‘One of my favorite things you’ve done was when you supported Cruel Summer SO much, I ended up starting The Eras Tour show with it. For old times sake, I’m releasing the live audio from the tour so we can all shriek it in the comfort of our homes and cars PLUS a brand new remix by @lpgiobbi,’ she added.

‘Thank you, so much, forever, wow, just thank you!!!,’ Taylor concluded her post.

Many fans reacted to the viral photo, with one writing: ‘That’s not Taylor Swift’s body’
