Yesterday (14 May), Foxes shared three red tiles on her Instagram, presumably a break on her profile to indicate a new chapter musically.
This afternoon (15 May) Foxes has shared a brief clip which sees her ask "What does your heart desire?". Allen has also shared a link to her website, which has a UK phone number for fans to call.
It's very likely that Foxes is due to follow up her 2016 LP All I Need, and fans are eager to hear even a taster after four years away.
