George Michael has slammed soccer star David Beckham as insecure - because he changes his style so often.

The former Wham! singer is happy with sporting just one image, and derides Beckham's constant fashion fluctuations.

Michael says, "It's okay for a woman to try new styles, but for a man? If I look at David Beckham - he looks fantastic, but permanently changes his look. All I can see is insecurity.

"No matter how great he looks, he is still insecure. Things like that should stop if you reach a certain age."
