Lorde has revealed that she was left a bit emotional after watching Bruce Springsteen cover one of her songs.

As previously reported, the US icon recently surprised fans by performing the 17-year-old's hit song 'Royals' whilst on tour in her home country New Zealand.

The track has been covered numerous times in the recent past, but it seems Springsteen's version struck a chord with Lorde.

She told news.com.au: "My Twitter went mental, everyone in New Zealand was like 'You can't believe what just happened'. It was so exciting, it was the highest honour. He's such an incredible songwriter. I got a little teary. It was very cool."

'Royals' was released as a single last year from Lorde's debut album 'Pure Heroine' and it topped charts worldwide.
