Campbell celebrates 40th Riviera style

Naomi Campbell turned 40 today and is reportedly celebrating in style on the French Riviera.

The supermodel is also marking the first anniversary of her relationship with Russian billionaire Vladimir Doronin, who is said to be throwing her a "sensational party".

According to The Daily Telegraph, Doronin has told friends the party will be full of surprises and bigger than Simon Cowell's 50th. Campbell spent the eve of her birthday on her partner's superyacht, which the Daily Mail reports costs £350,000 to charter for a week.
