"It is a struggle," Kim Kardashian said.

She continued: "I think when you do have a reality show, people assume that it's just a ton of bar fights and it has this negative connotation. In actuality, we definitely do fight and we're really honest and open with our family life.
"We pride ourselves in doing that, but I think you can be both … There are so many grounds that we want to cross. People think that you can't really be both at the same time, but we do our best to kind of break that."

The three sisters who star on Keeping Up With The Kardashians along with their mother Kris Jenner, step-father Bruce Jenner, and step-sisters Kylie and Kendall Jenner, were speaking on CNBC's Closing Bell programme.
Speaking of balancing work and home life, Kourtney Kardashian added: "I think my biggest struggle as a mom has been balancing the two. But I do think it's possible. I just think it's like you feel guilty. You have to find that balance. I used to feel so guilty every time I left ... but there is no cookie cutter way."
Kim added: "It could get tough after you have a baby. There [have been] so many times when I just didn't wanted to get up and work on something ... I just wanted to be home with my baby, but for me, I think I can speak for my sisters, it makes us feel good when we are out working."

Kim, who married Kanye West in a lavish Italian ceremony in May also discussed how married life has changed her priorities.
"You know, now that I'm married, I would so much rather spend time with my husband, my family, and my baby, than run around the world working for other people."
