Kim Kardashian West is reportedly creating a line of toy dolls based on her family.

The 37-year-old reality star - who has kids North, five, Saint, two, and seven-month-old Chicago with husband Kanye West - is exploring the idea of marketing a collection of dolls and has hired her eldest child as her ''chief doll officer''.

A source told the latest issue of America's OK! magazine: ''Kim's involving her daughter in every step of the process, from how the dolls look to their clothing.

''Kim wants to teach North that she's important and could lead a prosperous business someday, just like her mom. She wants to help her children find success outside the entertainment business.''

As yet, it remains unclear which members of her world-famous family - which also includes sisters Kourtney and Khloe Kardashian, as well as half-sisters Kendall and Kylie Jenner - will feature in the toy range.

Although Kim remains best-known as a reality TV star, she has branched out into other areas over recent years, including launching her own emoji business and creating a makeup line.

And the brunette beauty previously revealed that in spite of how she might be perceived, she's always regarded herself as a businesswoman.

Kim - whose reality show 'Keeping Up with the Kardashians' has become a worldwide hit - said: ''When the opportunity for our TV show came about, I wanted to do it to bring attention to our stores [DASH, which she opened with her sisters in 2006].

''I was thinking this might not last very long, but we'll grow a great business and expand online. I thought it would be great press. I didn't think it would turn into what it turned into.''

Kim also thinks that her work ethic has been one of the keys to her success.

She said: ''The reality is people don't want to get up and work. It sounds crazy, but I see it all the time.''
