Khloe Kardashian says her older sister Kim Kardashian is "not doing that well" during her self-imposed exile from social media after the armed robbery.
Kim, 35, is reportedly depressed that her reality TV show was suspended indefinitely.
Her situation was further complicated when a Halloween costume showing her gagged and bound in a white bathrobe swept the Internet on Monday.
"She's not doing that well," Khloe, 32, told daytime talk show host Ellen Degeneres during a taping on Tuesday.
“It’s incredibly traumatic what happened to her. Our family is super close and we’ll get through this together. It will take time.”
Kim's depression likely worsened after retailer Costumeish.com released a “Parisian Heist Robbery Victim Costume Kit” depicting her alleged robbery.
The kit comes complete with a long black wig, white bathrobe, mouth gag, 2 feet of yellow rope and a "$4 million dollar" plastic ring -- all for the low price of $69.99.
Kardashian claimed 5 masked men bound her hands and feet and locked her in a bathroom at an exclusive private hotel in Paris during Paris Fashion Week.
Doubts and suspicions began to creep in almost immediately when Kardashian's story kept changing.
First Kim said she was robbed by 2 men, then she said 5 men. She said the robbers locked her inside a bathroom -- which locks from the inside. Then she lied about the value of the jewels that were supposedly taken.
The discrepancies led Parisian police to call the robbery an "inside job."
The inconsistencies were too much for E! Network, which suspended the poorly rated Keeping Up With the Kardashians.
"They needed an excuse to cancel the show and this was it," whispered an insider who begged for anonymity. "The network was losing money hand over fist," the source added.
