Fans Are Just Realising Macaulay Culkin Is Now In His Forties And We Feel Old AF

Yep, everyone's favourite kid from Home Alone celebrated his birthday on Wednesday 26th August by turning 40. That's four decades old!

TBF, even Macaulay knew it would make us feel weird when he tweeted about his birthday saying: "Hey guys, wanna feel old? I'm 40. You're welcome."

The actor, who shot to fame at the age of 10 in the 1990 comedy Home Alone, and to be honest we've never stopped seeing him as Kevin McCallister.

And if the responses to his tweet, which at the time of writing had racked up 453.9k retweets and comments and 2.4M likes, are anything to go by, you guys are just as shocked as us.

"Me having a great day and then finding out that Macaulay Culkin is 40 years old today and I'm getting old," tweeted Paul O'Sullivan from the band Greywind, along with a video of a man getting kicked by a horse.

"Happy Birthday! Gonna go cry myself to sleep now," said one shocked follower, while another said: "I honestly can't want won't believe this. Who is with me?" said another.

"Oh my god I'm shook," exclaimed a third.

Us too, us too.

In a follow-up tweet, Culkin added: "It's my gift to the world: I make people feel old. I'm no longer a kid, that's my job."

Two years ago, Culkin reprised his role as Kevin McCallister in a comedic "remake" of the classic film where he revisited iconic scenes with a tech twist for Google. We should have noticed his age then, really.

We hope you had a great day Kevin!
