Literally. The 1D star's latest inking is a tea cup and a saucer - and we're not shy about the fact that we like a good brew on the omg! desk.
But the singer's new body markings go further than just being in honour of a cuppa, they're actually paying tribute to lyrics from the band's hit song 'The Little Things'.
Louis, 21, posted a picture of the tatt on his Instagram page with the caption: "You can't go to bed..."
The song goes: "You can’t go to bed without a cup of tea, Maybe that’s the reason that you talk in your sleep."
We can't get out from under the duvet without some PJ Tips either.
Louis teased fans last month that he was set to get another marking on his skin. He tweeted: "More tattoos soon !"
And he's not the only member of 1D to cover his body in inkings - with Zayn Malik and Harry Styles regularly adding to their tattoo collection.
Bandmate Niall recently revealed to We Love Pop magazine that he's struggling to keep up in that department.
He said: "Harry and Zayn are really going at it, aren’t they? Harry seems to have a different one every day.
"I did actually decide to get Made in Ireland in green
on my a*** cheek. I went to this place in LA but they wouldn’t do it."
