'one of those falling for a star starts working out after attention grabbing' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.

'feat with worker' is the wordplay.
'feat with' becomes 'stunt' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'worker' becomes 'woman' (woman is a kind of worker).
'stunt'+'woman'='STUNTWOMAN'

Can you help me to learn more?

(Another definition for stuntwoman that I've seen is " one fighting on set, perhaps".)

I've seen this clue in The Irish Times.
