Kendall Jenner worries that younger sister Kylie Jenner will have a baby with boyfriend Tyga

Big sisters are the best. They stick up for you when someone’s nasty to you, and they’re your go-to shoulder to cry on when that boy you like doesn’t text you back.

But who knew that if you’re Kylie Jenner, your older siblings will also act as an odd form of contraception!?

Kourtney and Kim Kardashian have been telling the 18-year-old EVERYTHING about being pregnancy and giving birth. Yep, even the nitty gritty bits. Unsurprisingly, it seems to have scared Kylie off of having kids reports Hollywood Life.

A source has said that both Kim and Kourtney ‘love to talk about the gross things that happen to your bdy when you’re pregnant and how messed up it gets after the baby’s born.’

‘They go on and on and usually send Kylie running from the room screaming.’

The source continues and says that ‘it’s their way of scaring her straight because hey know they can’t come at her directly.’

Despite Kim and Kourtney’s attempts to gross Kylie out from having a baby though, with the teen’s relationship with 25-year-old rapper boyfriend Tyga becoming more special, fellow big sis Kendall Jenner is worried about Kylie.

‘She knows Kylie is being careful and says she has no plans on getting pregnant, but she still worried she will make a mistake and end up with an unplanned pregnancy.’

Being her older sister, Kendall can’t help but worry.

‘Kendall teases her, saying she better not end up with an ‘opps baby.’

Opps baby – what a phrase eh?

Kylie Jenner is said to be ‘very easily influenced by Tyga’ and that if he wanted to have a baby right now, it wouldn’t take much to change Kylie mind. Eek!

We don’t know if Kyles wants a lil bambino or not, but we’re just gonna continue staring at her AMAZING bod!
