Girl teen idol embraces (4)
I believe the answer is:
enid
'girl' is the definition.
(girl's name)
'teen idol embraces' is the wordplay.
'embraces' says the answer is hidden in the clue (I've seen 'embracing' mean this (the solution is embraced by words in the clue)).
'ENID' can be found hidden inside 'teen idol'.
(Other definitions for enid that I've seen before include "- Blyton, twentith century writer" , "& 18 Down Children's author" , "Geraint's loved one" , "Dine with Ms blyton, writer" , "'... Blyton, children's author (4)'" .)
