reuters -Model Naomi Campbell

Naomi Campbell is desperate to settle down and start a family.

The supermodel - who has dated several famous men including Usher, Robert DeNiro and Sylvester Stallone - is ready to have a baby but is worried she cannot keep a man because of her fiery temper.

A source told Britain's Grazia magazine: "Naomi has always had a reputation of being demanding but there are many reasons why she's struggled to settle down. When she became famous, she was allowed to behave like a needy child and had people like Gianni Versace protecting her. Getting older means she has to deal with her issues."

Naomi, 36, is also said to be terrified by the thought that she may never become a mother.

The source added: "She is beginning to realise that her biological clock is ticking."

Last week, Naomi appeared in court to face assault charges. She is alleged to have hit her former assistant over the head with a mobile phone.
