In the explosive clip, Kim is shown fuming at her brother for his choice in a romantic partner, while Khloe calls their sudden engagement ‘f**ked up’.
With Kylie Jenner looking on, the 35-year-old called Rob and snapped down the phone at him, before delivering a very clear warning.
‘You make sure your girlfriend doesn’t publicly bash your sisters!’ she screamed, after Rob said he wanted ‘no fighting’.
In a previous trailer for the season, Kim was shown on the phone to an unknown person – now revealed to be Rob – saying: ‘I’m not going to let my sister get disrespected, it’s just not what our family does.’
The clips imply that 18-year-old Kylie – who is dating Chyna’s ex-fiance and the father of her son Tyga – was left feeling hurt over Rob’s relationship, and Kim stepped in to argue on her behalf.
But Kim and Kylie were far from the only family members who were unhappy with the situation.
