'I'm Kim Kardashian,' the video kicks off, before another clipped showed her strolling into the room in a semi-sheer, plunging dress as she shouts: 'The princess is in the building!'

A dark-haired Khloe, now 32, then quips: 'My sisters say I'm a b***h...' before she can be seen shouting at her family to shut up.

However, she then finishes her thought from before, adding: 'but I always have their best interests at heart.'

In her introductory clip, Kourtney can be seen planting a kiss on now-ex Scott Disick, with whom she shares three children: Mason, six, Penelope, four, and Reign, one.
