Vladislav Doronin and Naomi Campbell at 2008 US Open - Day 14, New York City, USA - 070908

The catwalk queen escorted her boyfriend Vladislav Doronin to a lavish magazine party in his native Moscow on Tuesday (25Nov08) - 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 (08), denied they were planning to settle down and start a family, with Campbell's lawyers insisting the reports were "absolutely false and fabricated".
