An infamous tweet from Melania Trump has suddenly changed after being online for more than six years, and the internet is bewildered.

The post, which was uploaded in 2012, initially showed a photo of a beluga whale peeking out of a body of water and was captioned, “What is she thinking?”

However, on Saturday, Twitter users were shocked when they noticed the image changed based on the device being used to view the post.

In a quick test, the following appeared as a whale when accessed with a Mac laptop, but became a giraffe when searched using an iPhone, meaning what readers see in this article depends on how they’re viewing it.

What is she thinking? pic.twitter.com/rFufrgMb — MELANIA TRUMP (@MELANIATRUMP) August 10, 2012

Twitter users immediately took to the platform with screenshots of the drastically different photos, confused by the change, which didn’t seem to have an explanation.

“How does that even happen??” wondered the Orlando Sentinel’s Steven Lemongello.

Ok, so the famous @MELANIATRUMP tweet of a beluga whale from 2012 has somehow mysteriously turned into a pic of a giraffe on my iPhone (Just noticed by a bunch of people tonight) but is still a whale on my Android. How does that even happen?? pic.twitter.com/CYQJduvhKg — Steven Lemongello (@SteveLemongello) December 30, 2018

Same Melania tweet on my iPhone & my laptop. It renders on mobile as the beluga whale (not dolphin) & on the right is the giraffe. Did she try to activate the Winter Soldier or something?

I swear this is not photoshopped. You know the famous Melania Trump “what is she thinking” tweet? You know how it’s, like, a picture of a beluga whale, right? Well, why has it suddenly turned into a giraffe?? Is anyone else seeing this???? pic.twitter.com/7ezImZFTfT — yung 2019 ben™ (@benicus_rex) December 21, 2018

Taking note of the mass hysteria, Deadspin decided to share an article it published last September on a 2012 tweet on the Chicago Cubs account in which the image was replaced with a pornographic photo of a woman.

This is probably why Melania Trump's beluga whale tweet now has a photo of a giraffe: https://t.co/6O9GBQAXnW — Deadspin (@Deadspin) December 30, 2018

The issue could have been an expired image ID in the URL of the tweet, Deadspin explained, adding that it may have been reused, being re-assigned from a ball player to the female in the racy photo.

As the outlet pointed out, the awkward glitch has happened to a series of other sports teams including The Dallas Cowboys, The Philadelphia Eagles and the New York Jets.

As for the first lady’s post, Twitter had a field day circulating the old photo that resurfaced after she rose to political significance in the White House, the giraffe giving it new life.
