Olivia Rodrigo continues to pay tribute to her influences while on tour. The teen pop superstar covered No Doubt's 1995 classic "Just a Girl" at her shows at the Metropolitan Opera House in Philadelphia over the weekend, days after she was photographed with No Doubt frontwoman Gwen Stefani at the Met Gala in New York. Rodrigo's performance is energetic and driving, delivering the urgency and angst of "Just a Girl" to an audience that likely wasn't even alive during its heyday. https://youtu.be/0naC_Hz4zYo During the Sour tour, Rodrigo has incorporated several covers of hits from her alternative pop predecessors, including Veruca Salt’s “Seether” and Avril Lavigne’s “Complicated.” The North American leg of the Sour tour will continue through May 27, ending in San Fransisco. Rodrigo will perform shows in Europe and the U.K. in June and July.
