Initially there is no alternative lady (4)

I believe the answer is:
tina
'lady' is the definition.
'initially there is no alternative' is the wordplay.
'initially' says to take the initial letters.
The first letters of 'there is no alternative' is 'TINA'.
(Another definition for tina that I've seen is " Ain't this a girl?".)
I've seen this clue in The Telegraph.
Want a hint initially instead of a full solution?
