Their wardrobes are usually worlds apart, but both brunette beauties stepped out in America over the weekend rocking a pair of red heeled ankle boots.
We first spotted Katie sporting her foot candy while popping to the shops in Greenwich Village, New York, on Friday (7 March).
The Dawson's Creek star opted for a casual look with faded blue jeans, keeping the chills at bay with a cream ribbed jumper.
She gave her ensemble a tough edge with a leather biker jacket before adding an oversized checked scarf and a studded handbag.
Meanwhile, Kelly was out and about in Los Angeles the same day, heading to a meeting with a pink folder in one hand.
Unlike Katie, Kelly opted for a slightly lower heel and made the most of the LA sunshine by going barelegged.
The model also donned a thigh-grazing, long-sleeved dress covered in a cute ditsy floral print, plus a Barbie pink mani.
She wore her hair down and flaunted daytime smoky eyes and a flourish of pink lippy.
So, fancy taking a tip from Katie and Kels and getting in on the red-footed trend?
We've fallen for these burgundy numbers, £74.99 from New Look, which tick all the style boxes thanks to their gold zips, buckles and cut-out details.
Or for a slightly simpler choice, check out these ankle boots, £80 from Topshop, which feature metal trims on the heels.
Would it be wrong to buy both?
