The 'Keeping Up with the Kardashians' star, 19, insists there is no rivalry between her and her younger sister, 17, and she bombards her sibling with text messages every day.

Asked about their relationship, the top model said: "If you really want the truth, I text Kylie so many times and I look like a desperate girlfriend or something because she does not respond to me. She loves me though so it's ok."

Kendall is used to being primped and pampered before runway shows, but insists she doesn't stress about looking bad on Instagram.

She told the May issue of GQ magazine: "Every girl knows, for that one selfie that gets posted, there's like a hundred that goes behind it. The worst thing you can do in a selfie, there's not really anything you can do bad in a selfie."

The brunette beauty also isn't worried about her fame fading in the future if her family's reality TV show comes to an end.

She said: "It's actually really hard for me to think of. But that day will come, and it'll be fine.

"I don't think it would be worse. Everything that happens is still going to happen, just minus the cameras."
