Hot scoops regularly knocked back Spice Girl (4)
I believe the answer is:
posh
'spice girl' is the definition.
(nickname of Victoria Adams in the Spice Girls)
'hot scoops regularly knocked back' is the wordplay.
'hot' becomes 'h' (abbreviation eg on taps).
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
'knocked back' is a reversal indicator.
The alternate letters of 'scoops' are 'sop'.
'h'+'sop'='hsop'
'hsop' backwards is 'POSH'.
(Other definitions for posh that I've seen before include "Elegant, stylish" , "Peterborough" , "This 13 [SPICE]" , "Of the wealthy classes" , "'opulent'" .)
