What we already know is being confirmed by Kim Kardashian. She accompanied an Instagram slideshow of stunning images of her and her daughter North West, age 9, with the phrase "It's North's world, I'm just in it," on May 12. The 42-year-old reality personality and businesswoman was dressed fiercely in all-black on the cover image of the carousel, posing with her mini-me in the entrance to what appeared to be a hotel room. Kim appeared to be too hot to handle while wearing a crop top that was cut extremely short, high-waisted leather trousers, and high-heeled shoes. She accessorized with large black sunglasses with a gold chain around the frames that dropped down in front like an extra-long necklace, black gloves, and a quilted Chanel handbag. Other images featured the well-known mother-daughter team doing further postures for the camera. The cutest picture might have been of Kim making a duck expression as her kid kissed her on the cheek. North pretended to be speaking on the black corded phone in the room in the final slideshow pictures. Maybe she was really ordering more Chanel bags while speaking to someone! Meanwhile, North was wearing her trademark wide-legged, distressed black jeans. She accessorized the pants with a leather blouse with a collar and buttons, her mother's Chanel bag scaled down, and black sunglasses. With the help of her go-to black platform combat boots, she gained a few inches. In addition to donning black eyewear, North added a gold chain belt as an accessory. Psalm celebrated his birthday earlier last week with a huge firefighter-themed celebration that included a ball pit, a balloon firefighter, a vintage firetruck (which Kim and Khloe Kardashian posed in together! ), a gigantic fake station setup, and more. Kim sent a kind note to her youngest and included it with pictures from the birthday celebration, which she published on May 9 and which can be viewed here. "Happy 4th Birthday, my beautiful smart curious baby boy Psalm," she said. "I'm really overjoyed that you choose to make me your mother. Every day I learn so much from you. I can't wait to experience life with you and that adorable grin of yours, complete with your tiny fangs, lol. The SKIMS founder went out with her firstborn just one day after being seen at Universal Studios with her 4-year-old son, Psalm, and Psalm's older brother, Saint, 7. They were there to celebrate Psalm's birthday. The West brothers won a number of plush animals from some Boardwalk-style activities they played with the trio, which were afterwards handled by their security staff.
