"Houseboat” star (5)
I believe the answer is:
loren
'houseboat star' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for loren that I've seen before include "Sophia - - (film star)" , "Sofia, Italian film actress" , "See 15" , "Sophia, actor" , "Sophia --, Italian film actress" .)
