Country superstar Lainey Wilson joined us fresh off her massive Qudos Bank Arena show, revealing she didn't go to sleep until 2am because the energy exchange with the crowd was so intense she couldn't come down. She opened up about working with her dear friend Dolly Parton (who has a custom one-sided headphone so she doesn't mess up her hair), why Australian crowds feel special because country isn't oversaturated here, and how her band leader wrote "Can't Sit Still" about her because he's watched her chase this dream for 10 years—and we made her prove she can actually sit still long enough to play Sing with us.
