The 'Keeping Up With The Kardashians' star is a big fan of the 35-year-old tour manager because he makes her mother so happy.

She said: "He's such a nice person, and it's just been so fun to see my mom happy."

Kris, 60, was very upset when ex-spouse Caitlyn Jenner, who was previously known as Bruce Jenner, underwent gender transition earlier this year following their divorce in 2013 after 22 years of marriage, but Kim, 35, believes she has moved on now.

She said: "Mom has had such a hard year, and it's been refreshing to see her have a good time."

The brunette beauty also admitted her relationship with Caitlyn is still developing.

She said: "It's a journey. It's always been an adjustment, but as time goes on our family gets stronger and we understand each other more. The communication is better, the place everyone is in now, it makes me really happy."

Kim is set to give birth to her second child, a baby boy, with husband Kanye West next month and despite being 'miserable' she says it's "one billion per cent worth it".

Asked how she's feeling, she told PEOPLE: "I'm so over it. Some women find pregnancy blissful. They feel sexy; they feel alive. I find it to be a miserable experience, and I'm always going to be truthful about that. I remember Kourtney saying how much she loved it, and I don't love one moment of it. And that's okay. It's 1 billion per cent worth it."
