The Kardashians are ''such a close knit family''.

Scott Disick - who has Mason, six, Penelope, four, and Reign, 10 months, with his ex-partner Kourtney Kardashian - is looking forward to the arrival of Rob Kardashian and Blac Chyna's little girl as the Kardashian-Jenners are so close.

He told E! News: ''We're all such a close knit family that all of our kids are more like brother and sister and not just cousins. It's bigger than 'just cousins.'

''I believe Rob's going to be an amazing dad. [I haven't given him] strict advice on anything. I think it's just something you need to figure out within time.''

Meanwhile, Rob's sister Khloe says her sibling is ''really calm'' about becoming a father.

She said recently: ''Rob is fine. He says he's really fine and calm about it, but I was like, 'It's OK if you're nervous!' I think anybody would be nervous. But he seems super chill about it, so that's good.

''Chyna keeps joking like, 'This is our baby!' Like with me too. So it's like, I haven't been getting prepared, but I'm like, 'Should I be putting a nursery in my house too?' Chyna's like, 'Are you so excited? We're having a baby soon!' And I'm like, 'Wait, are you kidding or am I really having a baby with you?'''

Khloe loves being an auntie to Kourtney's children as well as Kim's two kids, North, three, and Saint, 10 months.

She added: ''I love them all. It's such a great thing to have another baby just to have with us, it's great. But at first, they're just with the mom, like you forget about them. They're never around 'cause the other kids are so rough, they're like all toddlers, you know? I just want to fast-forward!''
