The new season of Keeping Up With the Kardashians graced its fan with one of the most dramatic fights between Kourtney and Kim after they exchanged blows and scratched each other.

During the iconic fight, Khloe took to Instagram to live tweet about the episode where fans discovered that Kourtney’s anger was misdirected and she was angrier at Khloe than Kim.

Khloe then tweeted out: “I would demolish Kourts a** lol don’t play. I’m 5’10”. She’s 5 feet on a good day.”

Blac Chyna then took to Instagram and seemingly challenged the 35-year-old mom of one.

She wrote, alongside a questioning emoji: “What about 5’2?”

Blac Chyna – whose real name is Angela Renée White – is that same height – hinting that she would fight the tall Kardashian.

Blac’s apathy towards Khloe could stem from the fact that Khloe is standing behind her brother as he fights for primary custody of his and Blac Chyna’s daughter, Dream.

In court documents, Khloe said her niece is “decidedly more aggressive” and “more in defense mode” during playdates with her cousins after spending time with her mother.

The Revenge Body host also claimed she heard Dream say she does not want to go back to her mom.

She stood behind Rob as he reportedly claimed that his 𝚋𝚊𝚋𝚢 mama, 31, has become so out of control she would spend $600 on alcohol almost daily – including downing an entire bottle of Hennessy.

He also accused her of snorting cocaine all while their toddler was present.

The model’s alarming behavior turned dangerous inside her home where she has allegedly chased people around with knives, thrown lit candles around the house and even hurled other sharp objects at her own hairdresser.

In addition to being a physical threat, Rob says his daughter’s personal hygiene has taken a turn for the worse and she has arrived to him with tangled hair, dirty nails and teeth that have not been brushed.

He even went as far as to say his 3-year-old has been “naked twerking, and acting out 𝓈ℯ𝓍ual positions that she said her mom taught her.”

Rob also stated in the court documents that he wants Chyna to submit to drug and alcohol testing 30 minutes before each visit with her daughter.

He also asked that the supervising nanny present be granted authority to end the visit immediately should any violence break out in front of Dream.
