Kendall Jenner just picked out her favourite niece, and ooft this is going to stir up some family drama

Get ready for some sisterly sass.

It's the age-old rule that you're not meant to have favourites when it comes to family — or at least that you're not meant to publicly reveal your fave family members. But it seems that today Kendall Jenner is a big ol' rule breaker.

In an interview with People, Kenny was spilling the beans on what life as an Aunty to perhaps the world's most famous babies was like.

Side note: Kendall is now an Aunty to nine nieces and newphews. NINE?!

During her chat she accidentally let it slip exactly which of her nine nieces and newphews is her favourite, and oh Lord, this is going to bite her in the ass...

Out of Mason, Penelope, Reign, North, Saint, Chicago, Dream, Stormi and True (what a line-up), Kendall named Kylie Jenner's little bundle of joy as her favourite.

Kendall then quickly covered up and jokingly said, "I love all of my nieces and nephews — I like that I can give them back!"

Nice save.

While we're pretty shook that Kenny let this information slip, we can't really blame her for picking Stormi, because HAVE YOU SEEN HER CHEEKS?!
