And while both ladies are usually hot on our style radar, this time their mismatched outfits failed to impress.
Kimberly - who recently launched a mineral make-up line - was joined by boyfriend Max Rogers as she posed before the event.
The 'Don't Cha' singer opted for an electric blue dress by AQ/AQ, which featured a plunging mesh panel and flared skirt.
And while we're all for a flirty frock, she threw too many colours into the mix by adding a burgundy clutch, white peep-toes and a neon mani.
A gold clutch and nude talons would have worked much better!
Meanwhile, Louise suffered a fashion fail in an oversized quilted top and armour-like necklace.
Her bizarre top didn't do her cute tartan skirt any justice, which she may have worn in support of the England v Scotland footie match.
Not even her juicy orange mani could save this look.
