In case you haven’t already heard the life-affirming news, Louis Tomlinson is going to be a guest judge during X Factor’s Judges Housesstagealongside his old mentor Simon Cowell.

But as if the thought of Louis on prime-time TV isn’t exciting enough for you, we’re also living for the sass he’s going to bring – including those cutting facial expressions of his.

Here’s 15 we’re hoping we see…

When a contestant inevitably tries to best a Whitney Houston song

Nice try.

When Louis is quite literally blown away by an amazing song

SAAAAAAAANG, girl.

When things get a little off-key and a lot uncomfortable

Hopefully minus any PDA-ing couples, though.

When he loves a performance so much that he transcends space and time

Fave GIF ever.

When Louis feels pretty ‘meh’ about it all

It takes a lot to impress him, you know.

When he gets slightly frightened by a crazy performance so just smiles and nods

Terrifying.

When someone covers a One Direction song

Don’t bother.

Or worse, when a contestant tries to make fun of 1D

A terrible decision, really.

When somebody totally nails their final audition

‘That was absolutely incredible’.

When it’s time to say goodbye to the joke act

See ya, wouldn’t wanna be ya.

And said joke act refuses to go without a fight

Louis isn’t interested.

When Simon goes off on a rant that lasts for approximately 10 years

Well, this is awkward.

When his favourite contestant lets him down right at the end

He’s not angry, just disappointed.

When Sinitta unavoidably turns up wearing a crisp packet as a dress or something

You just know this is going to happen as well.

And finally, when a contestant says they want to be bigger than One Direction

Good luck with that, pal.
