LACE VENTURA: The lingerie and techno-gadget worlds don’t often collide. But front row at the Elie Saab show, Chantal Thomass revealed she has designed a line of iPhone cases to be released for Valentine’s Day. She whipped out her own phone encased in a pink-and-black lace design. Down the row, Elsa Pataky said she had recently wrapped filming “Mr. Nice,” also starring Chloë Sevigny and Rhys Ifans. “Rhys was so much fun, I didn’t want to leave the project,” she sighed. Meanwhile, model-turned-actress Paulina Nemcova hinted she might have a project with Jude Law in the pipeline. “I haven’t signed yet, so I don’t want to tempt fate,” she said.
