Last month, Kris Jenner announced that her sister Houghton had died aged 65.

The siblings had an infamously strained relationship after being raised in San Diego, USA, by single mum MJ following her divorce from the girls’ father, Robert Houghton.

The difficult relationship between Jenner and Houghton has been well-documented over the years.

The ‘momager’s’ sister signed an NDA before attending Kim Kardashian‘s 2013 baby shower, but would then openly speak to the press, violating her family’s trust.

Houghton also derided Jenner’s cosmetic enhancements, telling In Touch: “She was heavy as a kid and became worried about her looks at age 15.

“The whole world knows it – Kris is vain.”

Back in April 2014, Houghton wrote on her Facebook (via Daily Mail): “Pray for Kris Jenner she needs it… crazy. She’s a nutcase. She doesn’t need prayers she needs sky vodka hahaha hahaha hahaha.

“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.”
