You better believe it!
Taking to Twitter to answer a series of fans' questions over the weekend, the gorgeous reality star revealed that she's just like us when it comes to snapping up a beauty bargain and she hinted that she's a real high-street girl at heart.
We've lost count of how many celebs pinpoint Giorgio Armani, NARS and Estee Lauder as their foundation favourites - it needs to last, after all - but model Katie mentioned that she rarely ever shells out, and that's because she's found a good'un.
In reply to a super-fan who asked her what make-up she wears on a daily basis, Katie revealed that she loves the cheap-as-chips stuff!
"I often wear drugstore make-up," she wrote, "and I love Rimmel foundation. It's full coverage."
Yep, you read that correctly - Rimmel. The best part though? No matter which one you choose (we love the Lasting Finish, FYI) you'll never go over budget, as £8.99 is the limit.
Katie also went on to reveal exactly what gives her that eye-popping, otherworldly glow and told us that she loves M.A.C's Strobe Cream, £10 as a highlighter.
Did you know Kim Kardashian is also a ha-uge fan?
For cheekbones that glisten, apply underneath your foundation or dot a little over your perfectly applied base using the soft pad of your middle finger.
Kate then cleared up what we've been dying to talk about - her ah-mazing power brows! When asked if she draws them on using pencils or pomades, Katie said absolutely not.
"I don't draw them on," she wrote alongside a laughing-crying emoji. "They are naturally thick. I just tint them hunny."
And there you have it.
