Down-to-earth about celebrities I see (9)
I believe the answer is:
realistic
'down-to-earth' is the definition.
(similar in meaning)
'about celebrities i see' is the wordplay.
'about' becomes 're' ('re' means regarding or about).
'celebrities' becomes 'alist' (A-list).
'see' becomes 'C' (the word for the letter, according to Chambers).
're'+'alist'+'i'+'c'='REALISTIC'
(Other definitions for realistic that I've seen before include "Practicable" , "Practical; true to life" , "Level-headed" , "accurate picture" , "Objective" .)
