Lorde added her voice this week to those celebrating Australia’s vote in support of equal marriage rights.

Lorde told the cheering crowd: “I’m very proud of you.”

In a non-binding vote earlier this month, 61.6 per cent of 12.7 million people said “yes” to extending marriage rights to same sex couples.

Marking the moment on stage, Lorde got emotional. “This is the crying show,” she said. “I don’t know if you know that.”
