The former Celebrity Big Brother star took to Instagram on Monday (26 September) during a trip on the water with her 'boatsies gang.'
And we couldn't help but feel a teensy bit jealous of a) what an amazing trip it looked like she was having and b) how ruddy fabulous she looked with barely a scrap of (if any) make-up on.
Casey looked every inch the model in her sunny selfie, sporting wet, tousled waves and glowing skin.
And while we can't promise she's not wearing a little slap, she looked gorgeously 'au naturel' if you ask us.
Casey takes her skincare routine pretty seriously and uses everything from high street bargains to high-end luxurious creams.
"When my skin is playing up, I apply Sudocrem (£2.99, boots.com) before bed and when I wake up in the morning it actually makes my face feel so much nicer," she once explained to us.
"I love using Clarins face wash, but I've also been known to splash out on Crème De La Mer Cleansing Gel, when my skin needs a bit of TLC."
"On days when my skin isn't too oily, I also apply Clarins Lotus Face Treatment Oil (£33, boots.com) as a delicious night treatment."
Casey also has great genes to thank for her fabulous skin. And keeping her brows perfectly groomed isn't a bad way to make sure you always look stunning when you're sans make-up, either.
We just hope she's protecting her skin from those damaging UV rays with plenty of high factor sunscreen...
