Strict type of ballerina, initially narcissistic drama queen withholding support (4,3,6)

'strict type' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'ballerina initially narcissistic drama queen withholding support' is the wordplay.
I cannot really see how this works, but
'ballerina' could be 'prima' (prima ballerina is a kind of ballerina) and 'prima' is found within the answer.
'queen' could be 'er' (abbreviation for Elizabeth Regina) and 'er' is found in the answer.
'support' could be 'prop' (prop up can mean to support) and 'prop' is located in the answer.
This may be the basis of the clue (or it may be nonsense).

'of' is the link.

Can you help me to learn more?
