Kendall and Kylie Jenner used to walk in on Khloe Kardashian having a shower.

Kendall, 20, wrote on her website: "We'd walk in on Khloé in the shower just to annoy her, haha."

The pair also picked on Kourtney during their younger years and the raven-haired star recalled taking her shoes because she had small feet.

She wrote: "Kylie and I were always running around, getting into trouble.

"When we all lived together in one house, the two of us would mess with our sisters by sneaking into their rooms. I remember we'd always steal Kourtney's shoes because she had the smallest feet."

But they never messed about with Kim's "evil" pet dog.

Kendall added: "And, last but certainly not least, Kim had a dog named Kiska - Kylie and I were sooo scared of her because she was EVIL. Good times! (sic)"

When the pair - whose mother is Kris Jenner and father is Caitlyn Jenner, who was known as Bruce during their childhood - weren't misbehaving they were enjoying themselves on holiday, and Kendall recalled one vacation with former boxer Sugar Ray Leonard, Khloe's godfather, and his family to Hawaii.

She added: "My first memories of my parents are kind of blurry. I just have a general memory of being in our first house - my favourite house - and all my sisters and Rob living there.

"My whole family and another big family, the Leonards, went to Hawaii one year. We stayed at this huge hotel with a million waterslides and I remember all we did was go on them over and over and over again!"
