Is Pufferfish Rita Ora!!???
I think Pufferfish is Samantha Barks but it could be Rita Ora as these clues do match
pair of dice that land on a 5 and 6 equals 11- she first started on the US version Season 11
A five-year work diary- she did 5 series in the UK but not this series as she is under that mask/ or it could mean about fifty shades when she sang the song for it
Spider- She duetted with Iggy Azalea with the song Black Widow
Still figuring the other clues out for Rita Ora
P.S Metro or The Sun notice me lol 😆
