Movie girl with two American soldiers (4)
I believe the answer is:
gigi
'movie' is the definition.
(I've seen this before)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for gigi that I've seen before include "Lerner/Loewe musical" , "1958 film musical from a Colette novel" , "musical from the 1950s" , "Movie" , "1958 film, winner of 9 Academy Awards" .)
