One's well-known but talentless (7)

I believe the answer is:

notable

'one's well-known' is the definition.
(notable can mean a famous person)

I can't explain the remainder of the clue.

(Other definitions for notable that I've seen before include "Star" , "Remarkable, worthy of comment" , "Prominent" , "Worth remembering" , "Striking" .)

I've seen this clue in The Guardian.
