New York, Dec 1 : English supermodel Naomi Campbell and her Russian billionaire lover Vladimir Doronin left guests on the beach outside South Beach''s posh Setai hotel gagging with their public display of affection.

The two were spotted kissing and cuddling like a pair of newlyweds, fuelling rumours of an engagement, the New York Daily News reported.

The catwalk queen kept flashing an emerald and diamond ring Doronin had just bought her.

She attended the Art Basel festival and the “In Fashion Photo” expo that was held on November 25, which displayed more than 50 photographs and illustrations of her from the past 20 years.

She was also expected to throw her after-party for the expo at the Cipriani sales center in the former Saxony hotel, but was dissuaded by the restaurant''s current legal woes. (ANI)
