Kourtney Kardashian gets angry as Kim plans North's 'kidchella' birthday at her house WITHOUT asking

It is fair to suggest that Kourtney, Khloe, Kendall and Kylie wouldn't have their current success without the help of their much more famous sister.

So perhaps Kim Kardashian thinks they all owe her one.

That seemed to be the case when Kim planned her daughter North's first birthday party in June this year at Kourtney's house, and didn't bother to ask her permission. 

In an upcoming preview of Kourtney & Khloe Take The Hamptons, Kourtney is seen getting enraged when she finds out about the bash, by receiving an invitation via e-mail.

'I cannot believe that Kim would have the nerve to throw North's birthday party at my house and think that I wouldn't find out about it,' a genuinely perturbed sounding Kourtney off loads to Khloe.

She added: 'I guarantee you that Kim has no idea that this e-vite was sent to me. But I am sure that they sent it to me on accident'.

It seems what annoyed Kourtney was that she hadn't even entertained guests at her house in the last two years, as had been waiting to spruce the place up and finish off her backyard.

'It's like she's beaten me to it,' Kourtney added. 'It's rude'.

Another clip reveals a showdown between the pair, as Kourtney arrives at her house to find Kim in her garden setting up tepees and a giant Ferris wheel for the tot's birthday soiree.

A vaguely surprised Kim says to Kourtney upon her arrival, 'What are you doing here?' to which she replies, 'What are you doing here? This is my house.'

'What is that thing on my grass that is going to probably ruin my backyard?' she adds.

Kim answered her, 'Kourtney, I will get you new grass, you are re-doing the landscaping anyway. By the time you get back from the Hamptons you wouldn't even know we were here.

'But how would you think to have a party here, when I told you, you cannot,' Kourtney fumes back.

Drama! Kourtney arrives at her house in a less than good mood when she finds Kim planning a party 

Kim is then interviewed about the incident on camera, where she says: 'Is this really happening right now? I would think Kourtney would have a heart and let me throw my daughter's first birthday party at her house. I just don't see what the big deal is.'

Back to the drama in the garden, Kourtney then quite rightfully points out: 'The fact that you think it's okay though, to have a party at my house and that I wouldn't know, you don't have the respect for your older sister that you should.'

Kourtney later added: 'I cannot believe that Kim would have the nerve to throw North's birthday party at my house and think that I wouldn't find out about it.'
