Flower carried by glamorous entertainer (4)
I believe the answer is:
ouse
'flower' is the definition.
(Yorkshire river)
'carried by glamorous entertainer' is the wordplay.
'carried by' indicates a hidden word.
'OUSE' is hidden within 'glamorous entertainer'.
(Other definitions for ouse that I've seen before include "River that joins the Trent to form the Humber" , "River at Lewes (Sussex)" , "Norfolk river" , "N English river (and S English river)" , "bird has lost its tail" .)
