Kourtney Kardashian came really close to canceling her 40th birthday party earlier this year due to a massive fight with her younger sister Kim. The mother-of-three was having a hard time in the weeks leading up to her fortieth birthday and felt emotional and anxious about getting older. Kourtney has been open with her feelings about it and has been seen breaking down in tears on several occasions on the current season of Keeping Up With The Kardashians. According to the reality star, she has never worried about getting older before, but this year she was feeling a bit lost as to where she is in her life.
In the last episode of KUWTK, Kourtney could be seen trying on outfits for her big birthday bash, wanting to wear something really special. Khloé, who was the one organizing the whole event, and Kim were both asked to give their opinion, and Kourtney's fight with Kim started with Kim being overly negative about every single outfit. The birthday girl felt like Kim was being unnecessarily harsh in the delivery of her opinions, and admitted that Kim's attitude added to the pressure of turning forty.
As reported by People, the fight escalated when Kim found out Kourtney's stylist had reached out to several designers with whom Kim had worked hard to build a relationship. Kim accused her older sister of copying her style, which Kourtney did not agree with at all.
With Khloé in the crossfire, the fight continued via text where the sisters called each other ungrateful, petty, and miserable. Kim also called Kourtney a "fake humanitarian" and said she had not contributed to the world at all, something which the Poosh founder felt was very hurtful. Kourtney could be seen telling Khloé that she felt extremely overwhelmed and not like herself and did not even want to celebrate or be around people.
Eventually, Kim realized that Kourtney was being emotional and sensitive in general from turning forty. She decided to reach out an olive branch in the form of a vintage Versace gown for her to wear on her birthday. Kourtney accepted the peace offering and ended up looking and feeling her best on her big day.
