Servant out of bed, you say? It’s not true (4,2)

I believe the answer is:
made up
'not true' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for made up that I've seen before include "Supplied" , "buried the hatchet" , "Highly delighted" , "trying to look attractive?" , "brought quarrel to an end" .)
