Entertainers sent heart out? Good ones! (9)

I believe the answer is:

strippers

I'm a little stuck... Click here to teach me more about this clue!

'entertainers' is the definition.
(stripper is a kind of entertainer)

'sent heart out? good ones' is the wordplay.
'sent' becomes 'posted' ('post' can be a synonym of 'send').
'heart' indicates the central letters.
'out? good ones' becomes 'rippers' (I can't justify this - if you can you should believe this answer much more).
The middle letters of 'posted' are 'st'.
'st'+'rippers'='STRIPPERS'

Can you help me to learn more?

(Other definitions for strippers that I've seen before include "They should remove the paint!" , "Women in clubs" .)

I've seen this clue in the Sydney Morning Herald.
