George Michael has acknowledged his use of cannabis can be a problem.

The singer says he is trying to cut down.

In an interview on Radio 4's Desert Island Discs, the pop star also revealed keeping his homosexuality hidden for so long from the public took a deep psychological toll.

As far as the music was concerned his top pick was Amy Winehouse who he described as "the best female vocalist he's ever heard".

Roxy Music, Gnarls Barkley, Nirvana, Pet Shop Boys and Kanye West were among other artists to receive an honourable mention.
