There is a person who hasn't got any talent or skills for a particular job, say, a reality show, comedy show or a news anchor (no offence).
The person stays on the job just because of their good looks which would help increase the number of viewers. Obviously the person was apointed for the good looks (lets keep that appointer off the topic).
So what would we call this person whose sex appeal is used to run the show. The person is also aware so he/she is not a victim, lets just say that.
She doesn't do anything on the show but flips her hair and throw some of the worst punchlines here and there. She's a --------- (of/on the show).
He used his good looks to charm the lady in a high positon to get his promotion. He's a -------.
She got appointed just flaunting her long legs. She is ------.
