Patrick Mahomes’ younger brother Jackson has left fans wincing after posting a cringeworthy TikTok farewell ahead of the app’s ban in the United States.

The Supreme Court is allowing a ban on TikTok to go into effect just days before President-elect Donald Trump is sworn into office for a second term.

The decision was confirmed on Friday despite the popular video-streaming giants arguing that a law banning their app unless it is sold by its China-based parent company violates users’ First Amendment rights.

Nevertheless, with TikTok now set to be outlawed from Sunday January 19 a number of American users are making the most of what could be their final days on the app – including Jackson Mahomes.

The brother of Kansas City Chiefs quarterback Patrick shared a farewell video to his 1.1 million followers on Friday, which shows him dancing and singing in the mirror to the song ‘Messy’ by Lola Young. 

‘Since the app is getting banned I thought yall would miss your favorite [creator] on the platform!’ he wrote as the caption.

However, fans were quick to mock Jackson over his goodbye video. 

‘Not a single person will miss that j***off,’ said one user on X.

Another posted: ‘Literally forgot he even existed until this popped up in my timeline. He didn’t have to say goodbye’.

‘Oh God, please,’ a third commented.

A fourth asked: ‘What goes on in someone’s head when they are posting a dancing selfie like this ?’

While one joked: ‘Starting to like this TikTok ban’.

Moments after the Supreme Court’s decision, Trump told CNN the fate of TikTok ‘ultimately goes up to me, so you’re going to see what I’m going to do.’

‘Congress has given me the decision, so I’ll be making the decision,’ the president-elect said.

But president-elect Donald Trump insists the final decision is his and he is yet to review it

In a post on Truth Social, Trump later said the decision was respected and that ‘everyone must respect it.’

But he added: ‘My decision on TikTok will be made in the not too distant future, but I must have time to review the situation.’

The Supreme Court unanimously upheld the federal law banning TikTok beginning Sunday unless it’s sold after holding that the risk to national security posed by its ties to China overcomes concerns about limiting speech by the app or its 170 million users in the United States.

A sale does not appear imminent and, although experts have said the app will not disappear from existing users’ phones once the law takes effect, new users won’t be able to download it and updates won’t be available. That will eventually render the app unworkable, the Justice Department has said in court filings.
