Louis Theroux is something of a national hero thanks to his incredible documentaries and superior use of social media. But while he’s been busy creating award-winning docs, another Theroux, with an equally impressive career, is better known across the pond.

Just in case you didn’t notice the matching - rather unusual - surname, Louis is related to Justin Theroux: the actor and screenwriter who also happens to be Mr Jennifer Aniston. Bells, ringing?

“We’ve known this for ages!” I hear you cry. But for those who may have forgotten his very important bloodline, Louis recently sent a very important reminder that he and The Girl on The Train star are totally best friends.

He tweeted “Being grilled by my cuzz over how to pronounce our last name. The-row? Theroo? #meaning?” along with a picture of himself and Justin in a very posed/intense-looking debate.

Um, it’s totally Theroo…right? Louis’ followers, when they weren’t fangirling over Justin, seem to think so.

Always Theroo, surely? — Giles Paley-Phillips (@eliistender10) November 26, 2017

It's pronounced "legend". — SweetChaiOfMine (@RishInProgress) November 26, 2017

This isn’t the first time the pair have name-dropped each other. In an interview with The Mirror in 2014, Louis admitted that he’s tagged along with his cousin in the hopes of meeting his celeb friends.

“I have been to a few A-list parties but not massively,” he said. “It’s not my life but it’s fun dipping in to it.

"You can talk to someone relatively famous and they say ‘What do you do? What do you do for a job?’ and I say ‘I make documentaries for the BBC’ and you see their eyes just glaze over.

"And then you think they just want to get rid of you.”

NEVER, Louis.

If anything can give him an ego boost, surely it’s Justin talking about living in his smart cousin’s shadow?

“I never felt bright,” the actor told The Telegraph in 2016. “I was always conscious that Louis, who I love and adore, was riotously funny along with his father, Paul.

“But I was sort of the red-headed stepchild. Louis and Marcel [Louis' brother] would sit around reading Chaucer at a young age and Louis tells this story of looking up at one point to see me eating a styrofoam cup.”

“I think I did then throw it up,” he says. “And in a weird way that sums up our different career trajectories.”

These two are the cutest.
