Coldplay just confirmed any speculation about a new album coming soon.

A couple days ago, a London fan posted a picture of Twitter of a mysterious advertisement found in a subway station that identified something as coming out “December 4th”.

Fans were VERY quick to notice that the image looks an awful lot like one that was on Chris Martin’s shirt at Global Citizen fest this past fall, as NME points out.

Today thehe band took to Twitter (Nov. 2nd), posting the same image. This either confirms the rumors, or just shows that the band is great at trolling the internet. We’ll put our money on the former.
