“Last night, I was talking about some Madonna performances, and I said, ‘At some point, everything becomes irrelevant.’ Like, no one even thinks about when she did ‘Like a Virgin’ at the V.M.A.s. That just becomes a standard, where it’s just like, ‘Oh, that’s her thing.’ So, I feel like now that I did the V.M.A.s, that just kind of became a standard for me, and then anytime I do anything else, they’re like, ‘Miley kept it tame tonight.’”
She's not calling her irrelevant. She's saying that once you do something ****ty to the extreme no one gets shocked anymore because everyone expects you to be a ****.
