North West might be just 5 years old—6 on June 15—but her life so far has been full of milestones many adults would be lucky to reach. She’s sat front row at Fashion Week, she’s starred in a campaign for Fendi, and now she’s officially made her red-carpet debut—without her mom, Kim Kardashian West, or her dad, Kanye West. Last night, the oldest Kardashian West child hit a step and repeat—aka the photo backdrop at red-carpet events—alongside a handful of very young friends.

North West posed next to her bestie and cousin Penelope Disick, Kourtney Kardashian and Scott Disick’s only daughter, and friends including Ryan Romulus and JoJo Siwa, the child star and alum of Dance Moms. North and Penelope were there to celebrate Siwa’s 16th birthday. The party, held at the W Hotel in Hollywood, was hosted by Nickelodeon, which will later air footage of it in a special on May 18.

For the occasion, North took a page out of her mom’s style book, wearing a pair of hot pink leggings and a belt bag slung around her shoulder, like a street-style star. She paired those with a sparkly green shirt, a pair of iridescent combat boots, and lavender eye shadow. Meanwhile, 6-year-old Penelope wore the rainbow in an sparkly track suit and matching combat boots. Apparently they got the sparkly memo, as JoJo wore a similarly shiny outfit: a sequined dress with a lightning bolt in the middle.

While the event marked North’s first red carpet unaccompanied by an adult, it’s hardly her first step and repeat. Back in September, the fashion wunderkind posed on a red carpet for an L.O.L. Surprise fashion show in Palisades Park. She also walked in the show, appearing as a life-size version of the Thrilla doll, alongside Busy Philipps’s daughter Cricket and Sara Foster’s daughter, Valentina. At the time, Kim explained North’s involvement, telling Harper’s Bazaar, “She loves to dress up like her favorite characters, so it was so exciting for her to actually become a real-life L.O.L. doll.” As for her fearlessness in front of the camera, she clearly gets it from her mom.
