The reality TV star insists her teenage half-sisters, who first found fame on 'Keeping Up with the Kardashians' nine years ago, don't take their luxurious lifestyles for granted and "know when things aren't normal."

Asked if she has concerns about the 19-year-old model and the 17-year-old aspiring singer because they grew up in the spotlight, the 34-year-old star, who has 23-month-old daughter North with husband Kanye West, said: "I think that is just their reality and I have to think about that in a different way now that I have my daughter because she was born into it also and not by choice.

"I think that having so many sisters that grew up differently than Kendall and Kylie, and always [being] there to talk about things, they know when things aren't normal. They know all their friends aren't just going on private jets, they know they are growing up with a life of privilege, but they really are super grounded and responsible."

Kim also claims that Kylie is still in school despite rumours she quit last year to focus on building her own empire.

She told 'Access Hollywood': "She's home-schooled. She has a year left. She goes to school every single day."

The starlet, who is dating 25-year-old rapper Tyga, recently admitted she got temporary lip fillers and Kim fully supports her.

She said: "I think it changed her confidence so much."

But she doesn't think Kylie will get any other procedures.

She said: "I think there is limits and there is boundaries for sure, and you have to know the difference. She did something that made her feel better about herself and that's kind of where you have to draw the line. I'm totally okay with that because I know that's where it stops for her."
