The US rapper has regularly been pictured with Kim, 30, and it is now claimed their meetings were being filmed for their latest E! reality show, where Kim and Kourtney are setting up a New York DASH store.
In a sneak peek clip of the new show, which airs on January 23, the rapper tells the girls he isn't sure they can get the store ready in time as there were only two weeks to go until it opened.
However it has been claimed that the girls made $100,000 on Black Friday and that the store is now one of the best-selling branches.
