The 'sophomore slump' may have claimed its share of budding popstars, but Lorde has officially sidestepped the second album curse spectacularly.

Melodrama, Lorde's new album, has gifted the NZ singer her first No.1 album in the US and Canada, and her second No.1 album in New Zealand and Australia, after 2013's breakthrough Pure Heroine.

The album toppled Katy Perry's Witness off the top of the US's Billboard chart, and slayed Ed Sheeran's overachieving Divide both in Australia and her home country.

The singer, real name Ella Yelich-O'Connor, took to Twitter to post an epic note in which she thanked her fans for the album's success.
