Bill Cosby has reportedly been quietly dropped by his agent, in a further blow to the US star's shredded reputation.

Deadline Hollywood has reported that Cosby has been dumped by his representatives Creative Artists Agency (CAA).

CAA is the top agency in Hollywood with a stellar roster of names on its books, including Cate Blanchett, Tom Cruise, Meryl Streep and Steven Spielberg.

Cosby is facing accusations that he serially drugged and raped women over a period of more than 40 years. He denies the allegations.
