Spoilt star with nerves getting cross (10)
I believe the answer is:
transverse
'cross' is the definition.
('transverse' can be a synonym of 'cross')
'spoilt star with nerves' is the wordplay.
'spoilt' indicates anagramming the letters.
'with' is a charade indicator (letters next to each other).
'star' after 'nerves' is 'nervesstar'.
'nervesstar' is an anagram of 'TRANSVERSE'.
'getting' acts as a link.
(Other definitions for transverse that I've seen before include "Extending across (the long axis)" , "go in 6 ac [CRISSCROSS]" , "Crossing" , "Crosswise" , "Extending across something" .)
