"She's a wonderful friend. She blows my mind," Emma added. "I mean, the amount of sheer stamina to do three and a half hours and perform 44 songs and to maintain the extreme energy of the audience — I've never seen anything like it."
As for whether fans can ever expect a collab between Taylor and Emma (who won an Oscar for her singing and dancing in La La Land), it sounds like a hard no.
"Oh, God, hell no!" she said. "I can't sing, like, for a massive stadium. Let's not even go down that road. She has insane talent — I could never do what she does."
