Text below the photo indicated it had been taken ten days before Christmas.

Kris and Karen have long endured a rollercoaster relationship, oscillating between taking public barbs at one another, to Kris lavishing her little sister with pricey gifts.

In 2016, Karen paid the ultimate compliment to the momager, getting an intensive face lift in order to ‘look like my beautiful sister Kris’.

She has frequently been outspoken when her sister Kris has riled her. In 2014, Karen told Radar that despite Kris and her estranged husband Bruce looking friendly there would be no reunion.

Karen said: ‘Bruce left. He walked out on her, and I think he’s not coming back. He couldn’t take the yelling anymore and stuff.’

And she said Kris was not taking the split well, adding: ‘I think she’s got issues right now because Bruce left her. ‘Kris is alone, she’s not dating. She’s not the type to run around.’

She made the comments after writing on her Facebook page in April 2014: ‘Pray for Kris Jenner she needs it…crazy. Shes as nutcase [sic].

‘She doesn’t need prayers she needs sky vodka hahaha hahaha hahaha.’ And explaining her somewhat harsh views, Karen said ‘I get p***ed off at her because she doesn’t respond to me. If you think your sister would call you back, she doesn’t. And it hurts me.’

However the part-time nurse did poke fun at herself too, in a May 2014 Facebook post, writing, ‘Be someone s crazy aunt…its fabulous! !! K [sic]’

Karen – who lives two hours from her sister in San Marcos, California – blamed her sibling’s celebrity status and hunger for fame and fortune.

She said: ‘I don’t care how much money you have or who you are, you’re my sister. I’m not afraid of her. I can’t get to her anymore. But I guess it’s the money.

‘She’s a huge celebrity and now she has changed. I’m not saying good or bad. But I’ve seen what it can do to Kris… ever since she moved to L.A.’

Admitting she has had run-ins with Kris – mainly to do with caring for their aging mother, Karen told MailOnline: ‘I called up Kris yelling at her, because I was like, “You need to help your mom more and you know it.” And I think that she kind of got the message.I was screaming – I don’t even care.

In 2014, the former air stewardess told Radar, ‘when you express a loving family and family values and a close family and my mom wants to live in La Jolla, buy her a condo, Kris! I don’t understand her. I never will. It’s just her personality.’

The attack followed a 2013 interview during which Kris told Radar: ‘Unfortunately, my sister has been dealing with demons for years.’

Resentment: Karen – who lives two hours from her sister in San Marcos, California – blamed her sibling’s celebrity status and hunger for fame and fortune

Kris, born Kristen Mary Houghton, was raised in San Diego with Karen, her only sibling.

Their single mother Mary Jo Shannon looked after them when their parents divorced. Kris was just seven.

In the star’s 2011 autobiography she said of her sister, ‘We loved each other, and we were there for each other through thick and thin, and to this day we are a part of each other’s lives.’
