'We don't need this!' Kylie Jenner listens in while Kim Kardashian blasts Rob over Blac Chyna's social media attacks on family

The Kardashian family were far from welcoming when Blac Chyna began dating Rob. Until, that is, she announced her pregnancy.

But with her instant admittance to the Kardashian 'inside circle', the bemused couple are abruptly learning there are certain expectations - as Kim makes totally clear in an upcoming episode of Keeping Up with The Kardashians.

Berating her brother as Kylie Jenner listens in, Kim hammers home the point that the couple are now expected to toe the Kardashian family line.

'We don't need this!' Kylie Jenner listens in while Kim Kardashian blasts Rob over Blac Chyna's social media attacks on family

The Queen Bee of the family gives Rob a serious talking to.

'I never get pissed and I'm so for you being happy but whatever Chyna and Kylie and all the drama that they have together, like that's for them to work out,' Kim tells him.

'Mom has bent over backwards doing all this stuff.'

Her comments came after Chyna mocked the food with which his mother Kris Jenner had stocked his new home - which she had purchased on his behalf using the family trust.

Intense: It's clear Kylie approves as the Queen Bee of the family gives Rob a serious talking to

Kim made her feelings clear.

'Mom is pissed, when you start publicly bashing my sister and mom, that's not cool. This is just unnecessary, this is not what our family does.

'Like there's way too much drama, so many haters in the world, we don't need this from our own inside circle.'

Rob responded: 'I didn't even know what was going on first of all. And I don't even think it's that serious.'

Unimpressed: Kim said 'Everyone has to just not be blasting people on social media. You two are a unit now so it looks like you're blasting mom and it's petty as f***'

But his big sister remained unimpressed.

'Everyone has to just not be blasting people on social media. You two are a unit now so it looks like you're blasting mom and it's petty as f***.'

Kim's anger was triggered by the videos shared on Rob's Instagram account in which he and his fiancée laughed rudely at a selection of food - from quinoa to oatmeal - which had been stocked in the cupboard of his new home. 

Making the call: Kim and Kylie went into Kris Jenner's garage for some privacy as they talked to Rob

Blac, 28, did not seem very impressed by the food that her 29-year-old had around the house in the clips.

'Bae what is this? What is that?' she says repetitively in the videos, as he adds: 'What the f*** is this?'

The couple couldn't stop giggling in the clips as Blac examined some fancy cranberry and hazelnut crackers, two pints of low-fat but sugary sorbet and packets of wheat tortillas.

She burst out laughing when she found a packet of quinoa at the very top of the pantry shelf.

Offensive: Blac Chyna blasted the food in Rob's new house... but it was put there as a gift by his mother 

'And y'all thought it was over, what the f*** is this?' she says, before Rob's hand came into view, showing her a pizza crust mix. 'What the f*** is that?' Blac added between giggles.

The model also checked out the reality star's spice collection and a packet of I Can't Believe It's Not Butter, before setting her sights on some Irish oatmeal.

'I mean I get his birthday is on St. Patrick's Day, but what the f*** is this bruh?' she shouts as Rob giggles in the background.

After they finished exploring the kitchen, Rob took a video of Blac talking to him seriously, while make-up free and dressed in a fluffy bathrobe.

'It's just sometimes in life you have to eat healthy,' she tells the sock designer, who has been shedding the weight after gaining over 100lbs in one year.
