Kourtney stuck the furry tash on her upper lip and donned a headscarf in aid of her weekly 'cooking club', which she has devised with pals.
Last night (5 June), the group held a Mexican themed night and Kourtney whipped up a storm in the kitchen.
Sharing a picture of her yummy offering, alongside one of herself wearing a costume, the mum-of-two tweeted: "My guacamole for my cooking club!
"We are having a fiesta tonight! Ole!"
We're quite impressed, not only by Kourtney's moustache, but by her rather impressive dish!
