Khloe Kardashian says her sister Kim Kardashian West is still "not doing that well" after being robbed at gunpoint.
The 35-year-old star was involved in a "traumatic" incident when she was tied up, put in a bath and had more than $10 million worth of jewellery stolen from her by five masked, armed men in Paris, France, last week.
Khloe has admitted it will "take time" for her sibling to recover.
She said: "She's not doing that well. It's incredibly traumatic what happened to her, but our family is super close and great and we'll get through it together.
"We do appreciate all of your guys' love and support. It will take time. It was horrible what happened to her."
Khloe admitted the incident has been a "wake-up call" for her social media-friendly family, who are often posting tweets and sharing Instagram pictures and Snapchat videos of their whereabouts.
Speaking on The Ellen DeGeneres Show, the 32-year-old star added: "It's just a wake-up call to make a lot of life adjustments. This is a really serious matter.
"For Kim I think it's really personal as to when that emotional, like, terror you could move on from.
"It's a wake-up call for all of us, but definitely [the focus is] just to make sure our sister is OK.
"Like I said, we're a family, we'll do this together. I think it's important to make those adjustments and to pull back a little bit I think is always smart."
Late last week, Khloe and her half-sisters Kendall and Kylie Jenner cancelled a number of planned public appearances in the wake of Kim's horrific ordeal.
A source said at the time: "Due to recent events and ongoing security issues, all signings have been cancelled."
Kim - who has three-year-old daughter North and 10-month-old son Saint, with husband Kanye West - is said to have told police investigating the incident that her robbers acted like amateurs after putting her in the bath and taking her out again before pointing a gun at her a second time.
