The glamour model applied a charcoal coloured mask all over her face before snapping a picture mid-beauty routine and sharing with her Twitter followers on Saturday (4 January).
With her highlighted locks swept into a top-knot, Katie looked chilled and relaxed (albeit a little grey!) while giving her complexion a hefty dose of TLC.
Alongside her snap she added the caption: "Saturday night,bath,mud mask,dinner then watching tv cuddles with all my children and@kieran0322 ,tea,biscuits mmmm."
Sounds like the perfect evening!
Now we have to say, it appears as if Katie's pamper session worked a treat.
The following day hubby Kieran Hayler posted a picture to Twitter of his gorgeous wife with her daughter Princess Tiaamii, and fans couldn't help but notice how clear and glowing Katie's skin looked sans slap.
Mud masks may remind you of high school sleepovers but they're actually a fab way to give your skin a deep cleanse, draw out impurities and unclog pores.
Plus you get the satisfying feeling of trying to crack them when they're ready to come off...
We like Liz Earle Deep Cleansing Mask, £14.50 for 75ml, which includes green clay, manuka honey, propolis and rose-scented geranium to help balance oily or combination skin.
Alternatively, why not check out Montagne Jeunesse Chocolate Masque, £1 a sachet? Ingredients include cocoa, Dead Sea salt and shea butter to keep skin soft and smooth.
Oh, and it smells like chocolate...
