One of the Astaires (5)
I believe the answer is:
adele
'one of the astaires' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for adele that I've seen before include "Female singer from London" , "Female English singer-songwriter, b. 1988" , "Popular female singer" , "Woman" , "Singer with albums titled 19, 21 and 25" .)
