In the interview, Kourtney adds that just when the family think there’s ‘nothing left to film’ for their TV show Keeping Up With The Kardashians ‘something will happen’.

After launching her own line for Pretty Little Thing, she admits she turned to expectant parents Kim and Kanye West for the green light on her designs.

She adds: ‘I text him photos and ask if he likes my outfit. Or, if we we’re all hanging out, I’ll show him different looks. He’ll give really good advice, like, “You’ve done that kind of look already, change those pants.”‘
