David Muir fans have been left gobsmacked by his age after he shared his response to affectionately being called ‘Daddy.’

The World News Tonight anchor has cultivated a huge fanbase thanks to his good looks – and now he has stunned them with his deceptively youthful visage.

In a recent interview, Muir casually revealed his age as he admitted that he is taking all the online attention in his stride.

‘People will forward TikTok videos, but only because they are laughing out loud at them and making fun of me and saying, “When did you become Daddy?”‘ he told People.

‘So, I don’t know whether that happens when you hit 50 or what, but I’ll take it as a compliment, I think.’

He continued to the publication: ‘Anyone who works with me knows that I am so uncomfortable even having to put on the tux. So, the fact that I survive those events is still a surprise to me without looking like a total nerd.

‘So maybe it’s lost on me, but I guess Daddy’s better than the alternative.’

Muir, who was born in 1973, turned 51 on November 8.

Social media were completely distracted by Muir’s remark about his age and begged him to drop his skincare routine.

Taking to X, formerly Twitter, one said in disbelief: ’50? He should drop the skincare.’

‘He’s 50!!?!??’ another quizzed while a third noted, ‘He looks good for 50.’

A fourth continued: ’50??? In human years???’

‘He does not look 50,’ a fifth said.

Another added in shock: ‘I’m sorry FIFTY???????’

Muir has been a main fixture on ABC’s World News Tonight since in September 2014.

He succeeded Diane Sawyer as anchor on the network, whose departure was part of a network reshuffle.

Shedding insight into life in the newsroom, Muir added to the People: ‘I generally have jeans on from the waist down.

‘So the first thing that we try to do is make sure my jeans aren’t showing…

‘I really don’t try to take myself too seriously but I always just joke, “Don’t tell anyone about the jeans and the boots!”‘

While there has been much interest over his personal life, Muir has largely kept details of his romances private.

It is not known whether he is currently in a relationship.
