The 33-year-old reality star - who welcomed her daughter True, whom she shares with Tristan Thompson, into the world earlier this month - has taken to her app to recall a story involving her younger brother Rob, in which a play fight turned nasty and she ended up hitting him so hard he lost a tooth.
Taking to khloewithak.com, the 'Revenge Body' star wrote: ''One time, Rob and I were in the backseat of the car, fighting the entire drive to Medieval Times - practically an hour and a half. We were fighting, whining and bickering, and I ended up hitting him in the face and knocking out his tooth. There was blood everywhere. My dad's friend was babysitting us, so needless to say this was quite the car ride for her.
''We still went to Medieval Times, but my dad definitely made me pay for it when it when I got home. Poor Rob!''
Childhood fights aside, Khloe has always been close with her siblings and fellow 'Keeping Up with the Kardashians' co-stars, including sisters Kourtney Kardashian and Kim Kardashian West, and half-sisters Kendall and Kylie Jenner.
In a separate blog post uploaded earlier this week, Khloe wrote a piece entitled 'My Wish for All of My Siblings', in which she spoke about how she wished her family ''eternal happiness''.
She wrote: ''I genuinely wish for all of my siblings that they find everlasting happiness in all that they do!
''Life is short, and at times, we put so many others before us, but one of our priorities should be our own happiness.
''Once you have that, it trickles down to everyone around us. I sincerely wish happiness and peace to my sisters and brother. (sic)''
For Khloe, despite becoming a first time mother this month, things have been less than perfect in her life, after video footage emerged seemingly depicting her 27-year-old boyfriend Tristan leaning in for a kiss with a mystery woman.
Recently, sources claimed she was ''torn'' on whether or not to stick by his side in the wake of the allegations against him.
A source said: ''She's not in a bubble of denial. She knows what's going on and is still trying to process it, but so far, she's managed to move past it and look forward.
''Khloe is very settled in Cleveland right now and is planning on staying another few weeks to a month at least. Of course, that could change, especially since every day there seems to be more stories [coming] out about Tristan.''
