Kim Kardashian and Kanye West’s 8-year-old daughter, North, gave her cousin True a brutally honest warning about turning 4.

“You are 4 years old. Four sucks,” North said in a video posted to Khloé Kardashian’s Instagram Story at True’s 𝐛𝐢𝐫𝐭𝐡day party Sunday.

Khloé, 37, was heard gasping from behind the camera at her unapologetically outspoken niece‘s remark.

North, who wore a T-shirt with her rapper dad’s face on it, may have been holding on to some bitterness from her own 4th 𝐛𝐢𝐫𝐭𝐡day when she celebrated amongst friends at a not-so-lavish Chuck E. Cheese in June 2017.

“Wow North West had a 𝐛𝐢𝐫𝐭𝐡day party at Chuck E Cheese! I’m jealous that I wasn’t the party hostesses,” one person tweeted at the time, with another adding, “They took North West to Chuck E Cheese lmao.”

Meanwhile, True’s other cousin Penelope, the 9-year-old daughter of Kourtney Kardashian and Scott Disick, had a much kinder 𝐛𝐢𝐫𝐭𝐡day message Sunday.

“Happy Birthday. We love you!” Penelope sweetly said to the camera.

Khloé documented her daughter’s over-the-top kitten-themed 𝐛𝐢𝐫𝐭𝐡day party, where decorations included plenty of pastel-colored balloons and flowers and giant feline displays.

There were also actual kittens placed around the party that attendees could cuddle, and the young guests enjoyed face-painting, dancing and jumping on a trampoline.

True’s outfit matched the decor, as she wore a Dior dress with a pink feather skirt and pink pigtail braids. Khloé coordinated with her daughter by wearing a Dior pink lace bustier top and matching pants.

Also seen at the party were Kim and West’s other 𝘤𝘩𝘪𝘭𝘥ren, Saint, 6, Chicago, 4, and Psalm, 2, as well as Rob Kardashian’s daughter, Dream, 5, and Kylie Jenner’s daughter, Stormi, 4.
