The posh pair were spotted hanging out at Professor Green's INK nightclub in the capital, where a bash was being held for ITV's The Complete Package - a male modelling competition judged by Abbey Clancy and model scout Cesar Perin.
Kimberley donned her favourite colour white for the event and nailed the smart-casual dress code in white jeans, a slinky camisole and a brown leather biker jacket.
She also offset her simple ensemble with an eye-catching and blinged out necklace, which featured large red stones and lots of sparkle.
Meanwhile, fashion-conscious Mark-Francis looked suave in a dark velvet blazer, which he teamed with a white shirt and a pair of jeans.
Bubbly blonde Kimberley got to know Mark-Francis during her time on series three of Made In Chelsea last year.
Since then she has gone on to feature in various photo shoots, attended dozens of showbiz parties and launched her very own swimwear line, which she of course modelled herself.
But although she has proven that there is much to do after a stint on Made In Chelsea, Mark-Francis is still enjoying his time on the E4 show and will be starring in the upcoming series 6 (returning on 14 October).
The witty magazine editor has been a firm favourite on the programme since its inception in 2011 and is often seen hosting lavish parties and bitching about style with his partner in crime and co-star Victoria Baker-Harber.
We can't wait to see what he and the rest of the MIC gang get up to when they return to our TV screens next week!
