Entertainer looks disheartened, confused, when grabbed by tot (4,6)
I believe the answer is:
folk singer
'entertainer' is the definition.
(folk singer is a kind of entertainer)
'looks disheartened confused when grabbed by tot' is the wordplay.
'disheartened' says to hollow out the word (remove centre letters).
'confused' indicates an anagram.
'when grabbed by' indicates putting letters inside.
'tot' becomes 'finger' (both are small amounts of alcohol).
'looks' with its centre taken out is 'loks'.
'loks' is an anagram of 'olks'.
'olks' put within 'finger' is 'FOLK SINGER'.
(Another definition for folk singer that I've seen is " Traditional entertainer".)
