Lovely soak (4)
I believe the answer is:
lush
I believe this clue is a double definition.
'lovely' is the first definition.
'soak' is the second definition.
(both can mean a heavy drinker)
(Other definitions for lush that I've seen before include "Habitual drinker (slang)" , "Drunk" , "Rich and juicy" , "Attractive" , "Like healthy plants" .)
