Unfortunately for the sparring pair, they both had very similar ideas as to what they should wear to the event.
Both looked gorgeous in their little white dresses although we couldn't help but notice the similarities between the pair.
Cheska of course added her trademark bohemian stamp to the outfit, accessorising with a tanned leather jacket and eye catching jewellery, where as Kimberly kept things simple with a matching clutch and heels.

It's no secret that the two aren't on the best of terms after Cheska made it her mission last series to derail Kimberley's relationship with co-star Richard Dinan.
Let's just hope the two stayed well away from each other last night.
The pair will be returning to our screens tomorrow night where it looks like things might kick off between Sam and Lucy Mecklenburgh following her accusation that new fiancé Mario has been playing away.
We can't wait!
As for Made in Chelsea, cast member Ollie Locke exclusively told omg! to expect to see more from our favourite posh lot much sooner than we'd expect. Hurrah!
