Minor celebrity in Gulf, very hot (10)
I believe the answer is:
blistering
'very hot' is the definition.
'minor celebrity in gulf' is the wordplay.
'minor celebrity' becomes 'B lister' (B lister).
'gulf' becomes 'G' (geographical abbreviation).
'blister'+'in'+'g'='BLISTERING'
I've seen this clue in The Independent.
