A girl from Cannes? (4)
I believe the answer is:
anne
'a girl' is the definition.
(girl's name)
'from cannes?' is the wordplay.
'from' indicates the answer is hidden within the clue.
'ANNE' is hidden in the letters of 'cannes'.
(Other definitions for anne that I've seen before include "One of the Bronte' tens" , "Queen, daughter of James II" , "Queen 1702-1714" , "Name of dead queen!" , "Last Stuart monarch, d. 1714" .)
