The models are reportedly creating a fashion range named after their BFF name 'CaKe' - a mash-up of their first names.
An unnamed source told The Sun that Delevingne and Jenner officially trademarked the name over the summer.
Apparently the models have already designed tops and hats with the logo, but plan to include other garments in the future.
“The ultimate aim is for CaKe to have its own stores in the UK and US," they revealed.
Delevingne and Jenner gave fans a glimpse of their CaKe logo back in June, when they wore matching 'CaKe Tour' t-shirts to fellow BFF Taylor Swift's concert at Hyde Park.
Hopefully their new venture will be more successful than Delevingne's most recent (and very controversial) foray into fashion.
