"Rolling in the Deep” singer (5)
I believe the answer is:
adele
'rolling in the deep singer' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for adele that I've seen before include "Female singer from London" , "Woman" , "Performer" , "Female English singer-songwriter, b. 1988" , "Popular female singer" .)
