The 34-year-old reality star has recently expressed her worries about the 28-year-old sock designer, who has retracted from the public eye in recent years, and branded him odd after he refused to leave his sister Khloe's house.

In the latest episode of 'Keeping Up With The Kardashians', Khloe ranted about their brother after he held a party in her home, inviting women who she described as "major w****s", who then vomited in the property.

She ranted: "Robert threw a party here last night - major w****s.

"Someone threw up in my house."

A shocked Kim then reacted to the news by admitting she was upset he refuses to spend time with them yet continues to socialise with others.

She replied: "'What? Like he won't leave the house or see us hardly but he'll have parties with other people?

"His life is so bizarre."

In the episode, viewers also saw Kim's husband, Kanye West, shoot the video to his song 'Only One', featuring their 22-month-old daughter North, which Kim said made her appreciate her "amazing" life.

Speaking about the video, she said: "I just think it is a really cool concept and I know it's going to turn out so amazing.

"It's so special to have North in a video with her dad and I think she looks so beautiful. I feel so blessed that we now have our little family - it's, like, so amazing that this is my life.

"It's so cool having these memories of North being so young and in a video with her dad. We can look back and just have this moment to last forever."
