Kim reveals which sister she wants to play herself in a movie

The 37-year-old star believes her youngest sibling - who is rumoured to be expecting her first child with boyfriend Travis Scott - would be the ideal person to tell her life story on the big screen.

Asked who would play her in the movie of her life, Kim said: "Maybe Kylie, keep it in the family."

However, Kylie, 20, may not to a convincing job of playing her big sister opposite the 'Keeping Up With the Kardashians' star's top choice for her husband, Kanye West.

Kim - who has kids North, four, and Saint, 23 months, with the rapper, and is expecting her third child via a surrogate - was very impressed with how well O'Shea Jackson Jr. portrayed his father Ice Cube in 'Straight Outta Compton' so would like to put the biopic on hold for long enough for her own son to grow up a little.

Discussing who could play Kanye with 'Extra' presenter Mark Wright, she said: "I really loved how authentic Ice Cube's son came across knowing his father, so maybe if it was in a little while, I could wait and see if our son has a lot of traits that he does."

Kim recently released three new fragrances, Crystal Gardenia, Crystal Gardenia Oud, and Crystal Gardenia Citrus, and she is pleased she and Kanye were on the "same page" when she was deciding what scents she didn't want to include.

She recalled: "I sprayed something that was a no and I walked by him in the bathroom and he was like, 'Wait a minute, is that your new fragrance? You have to ask me, because I do not like that'. I was like, 'No, it's a no, it's something I don't like either', so it was good we were on the same page."

The blonde beauty and her 40-year-old husband are preparing for the arrival of their third child, another daughter, and Kim has mixed emotions.

She said: "I'm really excited - and scared - for a new baby."
