'It's bizarre to me!': Blac Chyna is irritated at Rob Kardashian for wanting to focus on a fashion line instead of his weight problem in Rob & Chyna teaser

He is soon going to be a father to a little girl.

So it's no wonder Blac Chyna wants her fiance Rob Kardashian to focus on losing some weight and keeping Diabetes at bay instead of launching a fashion line. 'It's a little bit bizarre,' says Chyna.

The drama unfolds in a teaser for this week's Rob & Chyna.

She doesn't want him to do it: Blac Chyna is irritated at Rob Kardashian for wanting to launch a fashion line in a teaser for Sunday's Rob & Chyna

On it: The 28-year-old model calls his thinking 'bizarre'

'If you feel like you're being rushed into it, I feel like you should wait,' she says to the Keeping Up With The Kardashians vet.

'I mean it's something that we've been planning to do for a long time,' Rob replies.

'I just don't want you to put all this stuff on yourself and then you just be over it,' Chyna tells Rob.

He needs help! Rob then tells Chyna he's just trying to be 'more proactive,' but Chyna thinks he should 'wait'

She then explains, 'Rob needs to continue working on his health, his fitness, his sock business and so for him to try to go get a big, brand-new house and to start a new business is a little bit bizarre to me.'

Rob then tells Chyna he's just trying to be 'more proactive,' but Chyna thinks he should 'wait.' 

In a teaser shared earlier on Friday, Chyna and Rob fight over spilled French fries. 

The E! bad boy was not too happy with this and hassled his pregnant fiancee over it, asking her to pick the food up.

That's when the 28-year-old model told him he needed to 'relax,' which only made him more angry, leading him to call her a 'psycho' in a teaser clip for this week's Rob & Chyna.

What sets Rob off is that Chyna was more interested in her phone than his fries. 

'You gotta choose one, the food or your phone, either or,' Rob tells Chyna. 'Either or, what's more important?'

'These are my fries, those was your fries,' Chyna says.

'Yeah I know I'm saying you gotta choose one,' Rob says.

Nasty: That's when the 28-year-old model told him he needed to 'relax,' which only made him more angry, leading him to call her a 'psycho'

Henpecking her: What sets Rob off is that Chyna was more interested in her phone than the fries. 'You gotta choose one, the food or your phone, either or,' Rob tells Chyna. 'Either or, what's more important?'

And instead of letting it go, the only son of Kris Jenner, 60, gets annoyed that his wife to be doesn't 'help out' with picking up the fries.

'Didn't you just see I'm about to go down?' Chyna asks. 'I didn't see that s*** falling, God you gotta relax.'

The blonde beauty then tells Rob - who has stopped dieting since shedding weight earlier this year - that he should have been holding his own fries. 

'Yo you have serious anger issues,' Rob tells Chyna.

She is not amused: 'These are my fries, those was your fries,' Chyna says

She makes a good point: The blonde beauty then tells Rob - who has stopped dieting since shedding weight earlier this year - that he should have been holding his own fries

Trying to get her goat: The brother of Kim Kardashian then tells Chyna she needs to pick up his fries, but she is already doing so

He is then heard calling her a 'psycho.' She is expecting his first child, a daughter, on November 16.

Considering Rob's health issues - he had Diabetes but says he no longer has it - it's curious why he is eating fast food in the first place. 

The episode airs Sunday at 9 pm PST on E!

The two don't seem to be in bliss these days. According to UsWeekly, the 29-year-old Keeping Up With The Kardashians star and the 28-year-old video model are still living in separate homes in the Calabasas, California area.

InTouch Weekly added that Rob is 'faking' the relationship to get his $2 million salary for their spinoff Rob & Chyna which may not be renewed for a second season due to his reclusive ways.

Her pad: Chyna has her own property in Calabasas that she lives in with son King Cairo

On their E! show, Rob is kicked out of Chyna's home after she suspects him of texting other women. He then sets up house in the mini mansion Kris Jenner already bought him earlier this year.

The move seemed like it would be temporary, but UsWeekly has claimed it has not been.

'They think it's a healthier way to live,' said a source. It was added that they are fighting less now that they do not share a bed.

Loved up: They looked happy at their baby shower held in Woodland Hills on Sunday

Action! But the two reality TV stars had the Rob & Chyna cameras on them

And the insider was hopeful that one day they would live together in an even bigger mansion.

But for now, they will not share the same address. 

As far as their cloud-themed baby shower (which Kim Kardashian and her sisters did not attend but Scott Disick did), they were 'kissing the whole time,' added the pal.

Indeed, they did look happy at the party. But they also had Rob & Chyna cameras in their faces.

All about the green? InTouch Weekly added that Rob is 'faking' the relationship to get his $2 million salary for their spinoff Rob & Chyna which may not be renewed for a second season due to his reclusive ways; here they are seen in May

InTouch has alleged that the relationship is now fake.

And that Rob only wanted his $2 million payday for Rob & Chyna - which momager Kris set up - because he needed the money. He also wanted to compete with his sisters Kim, Kourtney, Khloe, Kendall and Kylie, who all have thriving careers.

'Rob wanted to make more money even if it meant pretending to be in a loving relationship,' it was stated. 

'They are scrambling to hide the truth about their messy, twisted relationship,' it was also claimed.
