'You know what happened to me at the ARIAs? I got into an elevator as I was leaving and this guy in the elevator goes "Oh Sophie!" and And I went, 'Um, no Sonia,"' the morning show co-host said.

Sophie also revealed she has the opposite problem, stating: 'Yeah I got Sonia, and I'm like, I'm not as smart as her.'
