The star’s loved up snaps comes just one week after her aunt, Karen Houghton, died ‘unexpectedly’ at age 65.

Karen was the younger sister of Kourtney’s mom, Kris Jenner.

Karen – who famously had a rollercoaster relationship with Jenner, 68 – was reported deceased to San Diego County officials on Monday, March 18, in San Marcos, California, TMZ reports.

The exact circumstances of her passing are unclear, with county officials attributing her death to natural causes for now.

Karen was Kris’ only sister, with the pair growing up in San Diego together raised predominately by mom MJ after her divorce from the pair’s father Robert Houghton.

On Tuesday, Jenner shared snaps with her beloved sister and wrote: ‘It is with the heaviest heart and deepest sadness that I share that my sister Karen passed away yesterday unexpectedly.

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

Part-time nurse Karen had become known as the black sheep of the family after she candidly opened up outside Kim Kardashian’s baby shower in 2013 and even did a jig for waiting reporters.

Despite signing an NDA for the event, Karen waxed lyrical about eating ‘marshmallow on a stick’, the rose cake at the event and the goody bag, saying Kim and Kanye West ‘gave out Rolexes’.

Karen had frequently been outspoken when her sister Kris has riled her.

In 2013 Karen claimed that Kris had spent an eye-watering $1million on plastic surgery, which stemmed from being self-conscious about her weight when she was younger.

‘She was heavy as a kid and became worried about her looks at age 15,’ Karen told In Touch magazine.

She added: ‘The whole world knows it – Kris is vain.’

Kourtney did not publicly acknowledge or speak out on her aunt’s death.

Her sister Kim Kardashian spoke out, breaking her silence on Thursday, March 21.

‘We just got pregnant naturally. It was an indescribable feeling. Shock, then super-happy, fear seats in, worry, but I remember then to have gratitude.’
