“I have to see my wife’s performance!”

Sabrina Carpenter has rocketed to international fame in the last year or so with a string of huge hits – but no matter how famous she is now, her best friend Joey King is always at her side.

King flew to Chicago to take her lucky nieces to the Carpenter's show at the United Center on Sunday, Oct. 13 — but instead of just swimming around backstage, the actress joined thousands of regular fans in the mosh pit and had the best time Time.

“I saw my wife perform in Chi Town last night,” he said Kissing Booth Star shared via Instagram. “I cried of course, she's just the smallest, cutest pop star I've ever seen.” And when a fan commented that it was strange that she was in the box with all the not-so-famous Carpenter fans, she explained that she just wanted to “mosh, babe!”

She added via Instagram Stories: “I love you, my Brina. Perfect girl. Perfect show. Feel so happy to see you shine.”

The two stars, both 25, share a history as Disney Channel alums but only recently became best friends when they hit it off at a charity event. “The funny thing is, she and I have always known each other and have always been friends,” King said Rolling Stone. “But it wasn’t until about four or five years ago that we became as close as we are now. But we’ve known each other for over ten years.”

King explained that it was Carpenter who first decided to break the ice. “Sabrina came to me and said, 'Hello, I'm Sabrina!'” she remembers. “The funny thing is that we weren't always very close. For the first few years of our friendship, we spent time together like once a year and it was the most fun thing in the world. We don’t know why it took so long for us to get as close as we are now.”

And it's not just a superficial showbiz friendship for the cameras – Carpenter even sang at King's wedding to the director Steven Piet in September 2023 and wrote via Instagram at the time: “My wife got married and I cried and cried. I was so lucky to be a part of your special day. I love you both very much, congratulations on your love.” At the ceremony in Mallorca, Spain, the multi-talented Carpenter sang “Tjugonde” by Amason, a Swedish band – in Swedish!

In fact, the two are always there for each other – King also appeared in Carpenter's “Sue Me” music video.

At the Chicago show, King dressed all in pink and shared many photos with Carpenter and her nieces. “Ugh I love being an aunt,” she wrote. And we're sure her nieces just love having a famous aunt who happens to be friends with a major pop star!
