After a mysterious 'snake' teaser was posted to her social media account yesterday, speculation has mounted that Taylor Swift is about to release a new single.

It's been four years since her huge '1989' album dropped, but the wait for new material may be over for fans - particularly since her frequent music video collaborator has been hinting at her return.

Joseph Kahn tweeted ahead of Swift's snake teaser yesterday, alluding to the fact that he has some insider info and may have worked with her in recent times.
