Charli XCX is giving fans a behind-the-scenes look into her life as an opener on Taylor Swift's current Reputation stadium tour.

On Sunday (June 3), Charli shared XCX World Part 1 on YouTube, a video series she describes as an "in-depth documentation of my life as a nerd." The eight-minute clip begins with the singer filming herself "freaking out" backstage on the May 8 opening date of Swift's tour in Phoenix.

"It feels really good to be on this tour full of girls," Charli says before sharing how nervous she is to perform on stage alongside Swift and fellow opener Camila Cabello. "I'm honored to be here."

Part one of the video series also follows Charli to a Los Angeles recording studio, where she continues to work on new music -- including her recently dropped surprise song "5 in the Morning" -- during her free time on tour. As noted in the description, the clip also features "lots of boob ... some cute studio moments with me and my fav A. G. Cook ... and me failing at dance routines."
