The 21-year-old model insists her brother-in-law will be ''OK'' after he was hospitalised last week after reportedly suffering a breakdown and says the rapper - who has now returned home - and her half-sister Kim Kardashian West are holding up fine.
She said: ''Yes, of course [he'll be OK].
''Everyone's OK. Everyone is doing OK, just praying.''
Kendall walked in the Victoria's Secret Fashion Show in Paris, France, on Wednesday (30.11.16) evening, but none of her famous family were there to see the lingerie spectacular after Kim was robbed at gunpoint in the city last month.
But the brunette beauty insisted she still felt supported by her loved ones.
She told 'Entertainment Tonight': ''It's [just] me. Yeah, no one is coming out but they're all - I've literally been texting with all of them, like, the past couple days.
''Everyone's, like, freaking out, I got so many flowers from, like, all my family members. So, yeah, I feel the love for sure from LA.''
However, Kendall wasn't completely alone as two of her closest friends, Gigi and Bella Hadid, also walked in the show, and the 'Keeping Up With the Kardashians' star admitted it was ''extremely comforting'' to know they were there with her.
She said: ''It's extremely comforting because these girls are genuinely my friends outside of work, outside of everything, so it's really awesome to be able to share that with them.
''Everyone is so supportive, which is really nice, because I feel like it could go the opposite and everyone's super cool and super supportive and everyone wants everyone else to succeed. So, it's really cool.''
Kendall walked in the show last year, as did Gigi, and though she was less nervous this time around, she was still very excited because the evening was a ''dream come true'' for her.
She said: ''I'm super excited, you know. This is my second time - it's a little bit different from my first.
''I feel like I know what I'm getting myself into this time, but I'm still really excited and, I don't know, it's been a huge dream come true of mine my whole life.
''I was talking to (Victoria's Secret CMO and executive producer of the fashion show) Ed (Razek) this morning, and I was saying how thankful I am to have my dream come true again. It's really awesome and I'm really happy.''
