But I also think that even pearl clutchers can listen to an album like that in their own solitude and find something that makes them smirk and chuckle to themselves.”She added that audiences at her concerts often include “many young women… screaming at the top of their lungs with their best friends,” calling the experience “just fun.”“I think about being at a concert with, you know, however many young women I see in the front row that are screaming at the top of their lungs with their best friends,. You can go like, ‘Oh, we can all sigh [in] relief like, ‘This is just fun.’ And that’s all it has to be.”Sabrina Carpenter’s Lollapalooza performances in South America, spanning Brazil, Chile, and Argentina, are scheduled for late March 2026.
