Last week, the internet reported - wrongly - that the Kardashian-Jenner empire was poised to expand Kate Moss-style, with the siblings creating a design line for Topshop.
The store quickly cleared up the rumour, confirming that they were actually in talks to be the exclusive UK stockist for the existing Kendall + Kylie fashion collection, which is currently stocked by PacSun in the US.
K 'n' K have made quite the impact on Topshop owner Sir Phillip Green, with Kendall sitting front row at last season's show and sporting a gorgeous Topshop Unique gown at the Met Ball.
And it appears the sisters have won him over with their business acumen, with the deal officially going ahead.
Their 'young, contemporary' line will land in selected Topshop stores globally - and online at TOPSHOP.COM - in time for high summer 2015.
Topshop has revealed that it will a 'comprise a capsule summer wardrobe, characterised by the girls' LA lifestyle and their modern, eclectic design aesthetic'.
