Dead gorgeous actress bleating about calories put on two pounds (6)
I believe the answer is:
bacall
'calories put on two pounds' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'dead gorgeous actress bleating about' is the wordplay.
I cannot really understand how this works, but
'about' could be 'ca' (abbreviation for 'circa') and 'ca' is found in the answer.
The remaining letters 'ball' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for bacall that I've seen before include "Lauren -, The Big Sleep actress" , "Lauren --, US actress" .)
