Cruz known as the "Queen of Salsa" (5)
I believe the answer is:
celia
'cruz known as the queen of salsa' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for celia that I've seen before include "Character in Tales from Shakespeare" , "Frederick's daughter" , "Daughter to Frederick" , "lady" , "Rosalind's cousin" .)
