There's no doubt that Kylie and older sister Khloe are close, but for Kylie to call her sister 'a mother figure' must have cut actual mum, Kris Jenner, quite deep.
Recent reports and rumours have suggested that Kylie's relationship with professional momager Kris is a little strained and the famous TV family face constant speculation that Bruce's ex-wife favours certain children while all but ignoring others, so perhaps 17-year-old Kylie's latest remarks aren't too shocking.
The blue-haired, luscious-lipped teen opened up abut her relationship with older sister Khloe, saying: "She's a huge mother figure in my life. She has always been the strictest on me- taking away my cellphone, having my passwords to everything."
Revealing how it felt to have someone so concerned about her well being and safety, Kendall's younger sister said: "It made me love and respect her so much because it showed she cared."
It looks like Khloe feels just as strongly about Kylie, calling the youngest Kardashian/Jenner sister "her heart".
Perhaps Kris will be pleased that Kylie feels like she has two mums in her life or maybe it will only add fuel to the fire.
