OMG! Sun's politics disturbed a writer on the paper (6,9)

I believe the answer is:

gossip columnist

I'm a little stuck... Click here to teach me more about this clue!

'a writer on the paper' is the definition.
I can't judge whether this defines the answer.

'omg sun's politics disturbed' is the wordplay.
'disturbed' indicates an anagram (the order of letters is disturbed).
'omg'+'suns'+'politics'='omgsunspolitics'
'omgsunspolitics' is an anagram of 'GOSSIP COLUMNIST'.

Can you help me to learn more?

(Other definitions for gossip columnist that I've seen before include "Newspaper writer" , "journalist" .)

I've seen this clue in The Telegraph.
