Absolutely. Lili's discipline is infamous. She's know to not speak for days before concerts. She said in an interview that when she is actively touring, she is like a hermit. She stops communicating with people to preserve her voice. She only sings. And she has insane diets... wearing a special belt that will alert her if she gains EVEN 1 pound. And she's been known to drink tea and eat half a jar of honey DURING her concerts. You can usually see a jar of honey near her... It's been parodied so much, but... it seems to be working. ❤️
The honey can be seen here. 🤣
