Love Actually is without a doubt one of the most loved Christmas films - but fans are once again getting mindblown over this little known fact about two of the actors in the film.
"Yearly reminder that Thomas Brodie-Sangster was only 5 years younger than Keira Knightley in Love Actually." a fan wrote on Twitter.
Keira was 18 years old when the film was released, while Thomas was just 13.
Some fans were struggling to come to terms with the news...
"This hurts my brain" one wrote.
"I refuse to believe this!" someone else said.
One thing is for sure - it might be time to just out the film and watch it again!
