Lorde teases new music to be released on Friday with new TV ad

The tiniest snippet of Lorde's new album made its way onto TV on Monday night.
The 14-second ad played on New Zealand channels, including Three, showing the Kiwi pop sensation eating something and slurping from a cup whilst in the back seat of a car. 
The video had music playing in the background, possibly hinting at the sound of her next single.
The ad says new music will drop in New Zealand on Friday.
Lorde reportedly shot a music video in Los Angeles in February.
The 20-year-old Kiwi superstar's last album, Pure Heroine, was released almost four years ago.
