Campbell's sparkler prompts engagement rumours

Naomi Campbell has sparked rumours she is set to marry her Russian billionaire lover - after showing off a huge emerald ring on her wedding finger.

The catwalk queen escorted her boyfriend Vladislav Doronin to a lavish magazine party in his native Moscow on Tuesday - and stunned revellers with a show-stopping sparkler.

Insiders at the bash claim Doronin was introducing the British beauty to his well-connected friends before they announce their engagement.

A source tells Britain's The Sun: "She was very pointedly looking at her ring and admiring it."

The pair, who have been dating since May, denied they were planning to settle down and start a family, with Campbell's lawyers insisting the reports were "absolutely false and fabricated".
