...and we can't help but think we've seen it somewhere before!
That's right. Doesn't the one and only Kim Kardashian own a v-e-r-y similar number? Oo-er!
Proving that she is every inch as stylish and daring as the world-famous mum-of-two, Katie poured her incredible curves into this barely there black dress that boasted a plunging neckline and a sheer skirt, draped over a high-leg body with a thong back.
Very cheeky, Katie. (Sorry not sorry).
Never one to ignore her fans and followers, Katie - who totally slayed the look - took to Instagram to reveal that she grabbed the eye-popping number from none other than Prodigal Fox (Danielle Lloyd Jessica Hayes are fans, just saying) and she captioned her rather risqué snap (hello boobs) with a positive quote.
It read, "Confidence isn't walking into a room with your nose in the air thinking your better than everyone else. It's walking into a room and not having to compare yourself to anybody in the first place."
Of course, people commented in their droves!
"You look unreal babe! One of my fave looks on you," wrote one Insta-user, while another tagged a friend and asked, "Do I buy this?"
Go on, treat yourself!
Katie isn't the only celeb to channel Kim Kardashian lately though, as her co-star Olivia Buckland emulated her stunning VMAs look earlier this month - and you can grab that exact dress from Prodigal Fox, too.
Kimmy, eat your heart out.
