Ridiculously inane woman (5)

I believe the answer is:

annie

'woman' is the definition.

'ridiculously inane' is the wordplay.
'ridiculously' is an anagram indicator (I've seen this in other clues).
'inane' anagrammed gives 'ANNIE'.

(Other definitions for annie that I've seen before include "Musical based on cartoon strip" , "1977 Broadway musical" , "Sharpshooter Oakley or musical orphan" , "Little orphan girl" , "Popular musical about Little Orphan" .)

I've seen this clue in The Sun.
