Insincere pair confronted (3-5)

I believe the answer is:

two-faced

'insincere' is the definition.
(I've seen this before)

'pair confronted' is the wordplay.
'pair' becomes 'two' (I've seen this before).
'confronted' becomes 'faced' (I've seen this before).
'two'+'faced'='TWO-FACED'

(Other definitions for two-faced that I've seen before include "Perfidious" , "Showing a double-sided visage to deceive" , "Duplicitous" , "Deceitful, double-dealing" , "Double-dealing, like Janus?" .)

I've seen this clue in The Telegraph.
