Kim Kardashian has revealed how Kourtney’s cruel taunts about ‘saggy breasts’ and ‘cellulite’ during her high-school years left her embarrassed and in tears.

Kim Kardashian opened up on this week’s The Kardashians about some of the cruel things her older sister Kourtney used to say about her in high school.

Kourtney, 44, and Kim, 43 – who Donald Trump called the most underrated celebrity – are recovering from last season’s bitter feud, which they resolved in Season 4.

The entire family gathers at the Bowlero Bowling Alley to celebrate Kourtney’s 44th birthday, when Kim reveals some painful insults Kourtney endured in high school.

At the beginning of the episode, others such as Simon Haqq, Corey Gamble, Malika Haqq, and Kim Kardashian arrive at the party, wishing Kourtney a happy birthday, and asks Kourtney to open her card as she hugs Simon. .

“I’m proud to call you my sister,” Kourtney reads. Hopefully it’s for all the other things I called you,’ as Kim said, showing the front of the card to the camera, adding, ‘Isn’t that so appropriate or what?’

Kim adds, ‘I wasn’t sure she would be mad at me for this card,’ but Kourtney insisted, ‘No!’ As Kim said in the confessional, “Finding funny cards online is a passion of mine.”

‘It was made for me and Kourtney,’ Kim said in a joint confessional with Kourtney, who added, ‘We used to say all the mean things. I had no feelings in my mind. All I would say is, “You’re so sick of cellulite!”

Kim continued, ‘Or like in high school she would say, “Oh, my sister has a big saggy butt, you’ll hate that!” And like those guys at school I like at a party and I literally walk away crying and say, “Bye guys.”

Kourtney turns to her sister and says, ‘Okay, I’m sorry about the past,’ Kim puts her hand over her heart and says ‘Thank you’ quietly.

The episode begins at the Bolero Bowling Alley, where Courtney arrives with her son Ren and several others to celebrate her 44th birthday.

Her mother Kris arrives with her grandmother MJ and they all wish her a happy birthday, as well as her stylist Chloe Degadillo, as Kourtney is seen wearing a “Birthday Girl” tiara.

‘I am turning 44. Honestly, 40 is the best age. “A lot of amazing things happened to me in my 40s and I’m so grateful,” Kourtney says in the confessional.

Khloe Kardashian arrives and takes a photo with her big sister, with Khloe adding, ‘I want to label this the “Filthy Rich Cattle Drive.”

“I can’t wait until Khloe joins me in her 40s next year,” Kourtney says in the confessional, as Kourtney asks Khloe if they should “do something lively” as Khloe brings up her sister. And turns it around.

“Khloe, put me down,” Kourtney says, and when Khloe asks why, Kourtney says, “Because… I’m so delicate,” as Khloe admits.

Although Courtney doesn’t reveal why she’s ‘delicate’, the preview for next week’s episode shows Courtney’s now-infamous pregnancy reveal in June.

Kourtney was at her husband Travis Barker’s Blink-182 concert when she flashed a sign that revealed she was pregnant.
