Stormy romance with leader of America being filmed (2,6)
I believe the answer is:
on camera
'being filmed' is the definition.
(I've seen this before)
'stormy romance with leader of america' is the wordplay.
'stormy' indicates anagramming the letters (stormy suggests disruption).
'with' means one lot of letters goes inside another.
'leader of' indicates taking the first letters.
The initial letter of 'america' is 'a'.
'romance' is an anagram of 'oncmera'.
'oncmera' placed around 'a' is 'ON CAMERA'.
(Other definitions for on camera that I've seen before include "Being shot" , "In process of being filmed" .)
