Brattish? Kylie Jenner is caught the midst of a tow with her older sister Kendall in a new promo for Keeping Up with the Kardashians 

A bedroom bicker is included in the short film that sees Kendall, 17, call her 15-year-old sister 'a brat.' 

And momager Kris Jenner is beside herself as she hears news of someone 'pressing charges' against her son, Rob Kardashian.

There's always a lot of drama Chez Jenner, but it seems the girls have faced even more upheaval of late. 

Striking out alone: Kendall might be growing apart from her sister...

'We all have bad times': Kris Jenner seems to be in a flap about son Rob 

Their mother confirmed that Bruce Jenner has moved out of their Calabasas mansion and into a beachfront pad in Malibu.

The 57-year-old told Access Hollywood Live that her 63-year-old husband needed to 'get away for a bit.'

'It does get a little congested in our house,' admitted the reality star, hinting that the rumours are true that daughter Kim, boyfriend Kanye West and their new baby have moved in to their house so Kris can help the new parents with daughter North, nicknamed Nori.

'I need a break!' Kylie Jenner says she needs space from Kendall

Zero to drama: Kris and Bruce are together in the promo but she's revealed that the pair are living separately 

Lippy: She seems to be taking a backseat for the moment but Kim popped up in the preview 

Kris appeared completely onboard with allowing her husband of 23 years to 'have fun' without her.

'It's a wonderful idea,' she said. 'It's amazing to have a little bit of space.' 

But she insisted that he slept at home most nights, although 'once in a while' he'll remain at the beachfront mansion, which is the abode of the couple's youngest children Kendall and Kylie Jenner.

Racing away: Scott's hobby seems to cause an issue 

Grounded: Khloe still seems to have her feet on the ground but for how long? 

Kris was evasive on the show about Kim's new baby, merely stating that the new family had moved into a 'private residence.'

But a family insider told RadarOnline.com: 'The entire household has been turned upside down because Kim and Nori have moved in. Bruce has been run out of the house! Kris didn't encourage him to stay either.'

'Wonderful idea': Kris was onboard with letting Bruce 'have fun' without her but insisted they sleep together at night 

Trouble in paradise: Rumours have been circulating that the couple, who have been married for 23 years, are headed for divorce 

Bruce 'decided to ditch the family home because he was constantly being told to be quiet because of baby Nori' so he thought it would be best to spend some time with his daughters and give Kim and Kanye some space.

The former Olympic gold medallist athlete is a big fan of aviation and often flies expensive scale model helicopters in his spare time but was told his mini-pilot fun would have to be out on hold while the baby settles in.

Bruce - who has been married to the Kris for 22 years - was seen buying a separate home in the latest series of Keeping Up with the Kardashians, but despite occasionally spending time apart the couple insist their marriage is rock solid.

Also in store on the family's reality show, Rob rips into Kris, Khloe, Kim and Kourtney for leaving him stranded, as reported on RadarOnline.com.

'I had to take a cab home cause the four of you are d***heads, you couldn’t come and pick me up,' Rob said. 

'This is really f****d up that all you guys thinking I was lying and didn’t come pick me up.'

Kris reminded Rob of his prankster nature as the reason why they didn't take him seriously.

'If you needed a ride, I would have come and given you a ride,' the family matriarch said. 'You’re constantly twisting the truth.'

Ensconced: The couple are staying at Kim's mother Kris Jenner's mansion in the Hidden Hills, Los Angeles
