Kourtney Kardashian is the eldest of the Kardashian sisters and has always had the reputation of being the most sarcastic and deadpan sister.
The 40-year-old mum of three has now sensationally quit Keeping Up With The Kardashians following a brutal physical fight with Kim, where she told Kim: "I will literally f*** you up".
The sisters kicked and punched each other and Kourtney jibed at Kim: “I don’t want to be near your fat a*s.”
She even scratched Kim, leaving her arm bloody and smacked Kim so hard she left a patch of bronzer on the wall.
But self-confessed "born b***h" Kourtney has always had a dark side, here is a look at some of her cruel taunts and savage jibes over the years.
For example, when her mum Kris Jenner decided to have a sexy photoshoot in a swimming pool and was feeling herself.
Kourtney immediately shamed her, telling her: "This is so embarrassing for your life and your soul", and demanding she stop.
She also made no secret of the fact she finds it funny when Kim sobs, because she has an "ugly crying face".
"I start laughing at Kim when she's crying because I just can't help it, she has this ugly crying face that she makes," she revealed during her confessional.
She also made a dig at Khloe's weight before she slimmed down, while Khloe was taunted as the "ugly sister" and was heartbroken about it.
While play fighting, Khloe laughed: "It's not over til the fat lady sings.
Kourtney shot back: "Khloe, start singing!"
It's not the only time she has body shamed her sisters, she also told Kim: "You think you're hot s**t because you have the biggest ass in LA - bye."
Khloe even asked Kourtney last year: "Seriously, what the f**k is wrong with you? Why are you so bitchy these days?”
And Kourtney responded, “I’m a born b***h.”
She also admitted to having no friends, but insisted she was glad about it.
Kourtney is also a prankster, but can take things too far, such as when she threw her sister Khloe's clothes off a balcony.
Khloe screamed: "This is couture!" as Kourtney threw thousands of dollars worth of clothes off the building while cackling.
During a recent fight over a photoshoot, Kourtney called her family "f***king b*****s".
When Kim branded her "the least interesting to look at", Kourtney replied: "You're a very distraught, evil human being.
"I don't want to see you, okay? I don't agree with you you are as a human being."
Savage!
