Lily Allen's father has warned her never to take hard drugs. British comic star Keith Allen suspects his daughter has taken cocaine and smokes marijuana but has told her to avoid substances like heroin and Ketamine, otherwise she could end up like her troubled pop rival Amy Winehouse.

When asked what advice Keith gives his 22-year-old daughter, he replied: "Have you ever met Lily?!"

Lily Allen has offered her support to troubled star Britney Spears.

The "Smile" singer says watching twice-divorced Britney - who lost custody of her two sons, two-year-old Sean Preston and one-year-old Jayden James earlier this week - go through such a difficult time is deeply saddening.

Kate Moss and Lily Allen had to be separated after a dramatic fight over Courtney Love on Tuesday.

The pair got into a heated debate at London's The Groucho Club when Lily attacked Courtney for her feud with Kelly Osbourne and Kate angrily defended her friend saying she was a "great woman."
