The supermodel has asked her lawyers to take "King of Botox" Dr Jean-Louis Sebagh to the High Court.
Her complaint concerns two articles in Hello! magazine claiming she was one of Dr Sebagh's clients and endorsed him. Campbell's lawyer Gideon Benaim told The Sun: “Our client Miss Naomi Campbell does not endorse Dr Sebagh’s products.”
The doctor's star clients include Madonna, Elle Macpherson and Meg Ryan, but Campbell has denied having plastic surgery of any kind. “I don’t need it because ‘black don’t crack’," she reportedly commented. "My grandmother has fantastic genes and only about one wrinkle."
Dr Sebagh – an early 1990s pioneer of the Botox anti-wrinkle technique – has refused to comment.
Campbell is said to be seeking a minimum of £50,000.
