Reckless sweetheart losing heart (6)

I believe the answer is:

daring

'reckless' is the definition.
(I've seen this before)

'sweetheart losing heart' is the wordplay.
'sweetheart' becomes 'darling' (I've seen this before).
'losing heart' suggests removing the centre.
'darling' with its middle removed is 'DARING'.

(Other definitions for daring that I've seen before include "Audacious - bravery" , "Risky" , "Derring-do" , "A grind (anag.)" , "Venturesome" .)

I've seen this clue in The Telegraph.
