Highly delighted? Not true (4,2)

I believe the answer is:

made up

I believe this clue is a double definition.

'highly delighted?' is the first definition.
(I've seen this before)

'not true' is the second definition.
(I've seen this before)

(Other definitions for made up that I've seen before include "Promoted" , "brought quarrel to an end" , "Chuffed" , "Highly delighted" , "mended fences" .)

I've seen this clue in The Telegraph.
