Kourtney Kardashian has admitted her sister Kim is still "not doing great" during an awkward live TV interview

Speaking on Australia's 'TODAY Extra' show, Kourtney said: "She's not doing great. I think we're all really still shaken up and I just - you know, I think she has a big supportive family and I know that all the traumatic things that we've been through, we get through them together as a family.

"And that's what family's all about."

But before Kourtney made the comments about Kim's wellbeing there was an awkward moment during the interview when co-presenter David Campbell asked how the 35-year-old star was, and Kourtney looked stunned before replying: "Ummm."

Someone could be heard speaking to Kourtney - who has three children Mason, six, Penelope, four, and Reign, 22 months, with Scott Disick - but it was not clear what they said and the host continued to ask about her sister.

After a moment of silence, David's fellow presenter Sonia Kruger said "it looks like Kourtney doesn't really want to go there with that question", and he said: "I think she's blanking me, I think she's totally blanking me on that question."

Sonia insisted: "I think there's probably a PR person there saying, 'Don't talk about it.' "

He added: "She could just say her sister's fine."

Sonia added: "Anyway, we thank Kourtney for her time this morning."

This comes after their sibling Khloe Kardashian, 32, made similar comments about Kim during an appearance on US TV earlier this month.

Khloe 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."
