Khloe Kardashian says her older sister, Kim Kardashian West, is “not doing that well” more than a week after she was held up during a Paris jewellery heist.

She is also suing a gossip site over reports the theft was staged.

During an appearance on Tuesday’s Ellen DeGeneres Show, Khloe Kardashian described the incident as being “incredibly traumatic” for her sister.

The Kardashian clan has been unusually quiet on social media in the days since the robbery, and Khloe says the incident is “a wake-up call to make a lot of life adjustments”.

She says the family is going “to pull back a little bit” and make sure it’s “protected as well as possible”.

The reality show Keeping Up With the Kardashians is on hold following the robbery.

Police say armed robbers forced their way into a private residence where Kardashian was staying in Paris last week, tied her up and stole $US10 million ($A13 million) worth of jewellery.

The celebrity gossip website MediaTakeout claimed she lied about the hold–up, reporting she staged the attack.

Kardashian has now filed a lawsuit in federal court in New York accusing the site of having no “factual support whatsoever”.

The lawsuit, which seeks unspecified damages for defamation, names both the site and its founder, Fred Mwangaguhunga, as defendants.

Mwangaguhunga refused to publish a retraction and an apology “for calling her a liar and a criminal,” the lawsuit said.

No arrests have been made over the robbery. 

Meanwhile her fans have reacted to horror over a dress–up company’s plan to sell a Halloween costume based around her ordeal.

Costumeish.com has released a “Parisian Heist Robbery Victim Costume Kit” which includes a short white robe, black wig, “$4 million” ring, sunglasses, a gag and a rope.

The move has sparked a wave of negative reviews saying the company should be ashamed of itself.

It’s the same company that sold Cecil the Lion costumes.
