Lorde takes on the seductive role but ultimately her teenage angst sees her tying him to a chair and kicking him into a pool, before setting the pool on fire.
Spy spotted an uncanny resemblance between the actor and her longtime musical collaborator, Joel Little.
But her video co-star is in fact Israeli-born British actor Iddo Goldberg, whose acting credits include playing the role of Isaac Walton, aka "Isaac the Fornicator" in TV series Salem.
He has also appeared in popular shows such as The Bill, Holby City, Little Britain, Secret Dairy of a Call Girl, Waking the Dead and NCIS. His film credits include Run Fatboy Run.
The 40-year-old is married to bombshell Ashley Madekwe, who stars in Revenge.
Sources close to Lorde and her partner of two years, award-winning photographer James K Lowe, said the chart topper's real-life beau was less than impressed with the cavorting for camera.
But Lowe did not respond to an approach for comment.
