Ed Sheeran has made a mysterious return to social media, exactly one year after embarking on a self-imposed break -- but why?

The "Thinking Out Loud" singer uploaded a blue box across his various social media platforms -- Instagram, Twitter and Facebook all feature the the same image -- with no caption attached, making for a cryptic post.

Fans have already interpreted the activity to hint at a forthcoming album from Sheeran, as his last post on Instagram (dated December 13, 2015) indicated a new release was "on its way" and would likely drop in the fall. While winter doesn't technically begin until December 21, we're quickly edging out of autumn and there's nary a Sheeran single to be seen.

The "Tenerife Sea" singer first announced he was institution a social media break back in December 2015, writing, “I’m taking a break from my phone, emails and all social media for a while, I’ve had such an amazing ride over the last five years but I find myself seeing the world through a screen and not my eyes so I’m taking this opportunity of me not having to be anywhere or do anything to travel the world and see everything I missed."
