Mark Hoppus Is Tracking Vocals In The Studio with All Time Low

All Time Low have been locked away in the recording studio for a couple of weeks working on their new album and it looks like that Mark Hoppus maybe featured on it.

The Blink-182 bassist posted a photo from the vocal booth in studio yesterday (October 17th) with the caption "it's me vs this thing today" with the members of All Time Low tagged.
