Olivia Wilde suffered a wardrobe malfunction that almost saw her fall as her heel got caught in her gown at the San Sebastian International Film Festival premiere of her new film, Don't Worry Darling. The House actress, 38, who recently dubbed split rumours from Harry Styles as 'nonsense', stunned at the premiere at the Victoria Eugenia theatre in Spain during the 70th San Sebastian International Film Festival on Friday in an emerald green dress.
