They warn us the lady's also backed into it (7)

'they warn us' is the definition.
The definition suggests an adverb but the answer is not.

'lady's also backed into it' is the wordplay.
'lady's' becomes 'hers' (her refers to a woman).
'also' becomes 'too' (synonyms).
'backed' says the letters should be written in reverse.
'into it' means one lot of letters goes inside another.
'too' backwards is 'oot'.
'hers' placed around 'oot' is 'HOOTERS'.

'the' acts as a link.
