The 'Keeping Up With The Kardashians' star wasn't impressed with her older sibling's driving skills when she took charge of the vehicle during a road trip with Khloé Kardashian to Palm Springs earlier this year.

She wrote in a blog post on her official website: "On the way there, we stopped at In-N-Out - the best cheese fries! FML. It was Khloé's first time ever at In N Out! Kourt isn't exactly the best driver - we kept making fun of her for not being able to drive while eating fast food, lol (sic)"

However, the 36-year-old television personality enjoyed a chance to spend time with her two sisters as they find it difficult to relax together because of their "crazy schedules".

She added: "Kourt, Khloé and I have such crazy schedules, so I love when we all get the chance to take a trip together. (sic)"

During their visit, the trio managed to fit in some shopping and visit their grandparents' old house.

She shared: "We went vintage shopping at Thirteen Forty-Five and we even got to visit our grandparents' old house, which was a special experience."

Whilst the sisters support each other unconditionally, like all siblings, they get into fights and recently, Kim blasted her sister Khloé as a "big bully".

Khloé said: "It's just interesting how I don't see you guys a lot. I take the time to come here thinking, great, this is time that I get to be with my sisters and my nieces and nephews and do all these things."

Kim ranted: "You're so annoying. It's like, shut the f**k up! You're the negative one, just saying how awful we are. You're like a big bully that bullies all of us!"

And Khloé fired back: "I'm over all you people now - ungrateful family members that I can't."
