Lara Stone wears wedding ring to Cannes amfAR gala

CAP D'ANTIBES, France, May 22 (UPI) -- Lara Stone surprised fans by wearing her wedding ring to an amfAR gala this week.

The 31-year-old Dutch model attended the organization's 22nd Cinema Against AIDS fundraiser Thursday. The event occurs each year during the Cannes Film Festival to raise money for AIDS research.

Stone stunned in a shimmering gold gown and partied with the likes of Karlie Kloss, Doutzen Kroes and Eva Longoria. Several photos from the fundraiser show the model with what appears to be her wedding ring on her left hand.

News of Stone and husband David Walliams' rumored separation broke in March. The couple married in 2010, and are parents to two-year-old son Alfred. Stone previously told Harper's Bazaar she doesn't have "anything else to wish for" than her house, husband, job and baby.

Stone is known for her runway work with such brands as Givenchy, Chanel and Balmain. She has held campaigns with Givenchy, Prada and Versace fragrances and Calvin Klein, and appeared in Vogue Paris, Vogue U.K. and W magazine.
