Kim Kardashian West doesn't "trust" Kylie Jenner to babysit.
The 17-year-old star loves being an aunt to 21-month-old North - her older sister's daughter with husband Kanye West - but she admits her sibling won't let her take care of the little girl on her own.
She said: "Kim doesn't trust me like that."
The two half-sisters are often compared because of their similar physical appearances but Kendall insists she is "completely different" to the 34-year-old beauty.
She told the UK's Grazia magazine: "When people say, 'Kylie is exactly like Kim', they don't really know me. We're opposite sides of the spectrum. We're completely different."
The 'Keeping Up with the Kardashians' family all get along well and regularly seek out opinions from one another.
Kylie said: "Before Kim dyed her hair blonde, she sent a text to us all asking if she should do it.
"She has such a perfect face, so I love it when she gets creative. I thought it looked cool."
While Kim may not trust Kylie to babysit North, she clearly has more confidence in some of her other siblings, as it was recently revealed her sister Khloé Kardashian, 30, was named as the youngster's godmother when she was baptised in Jerusalem earlier this week.
