Liv Tyler flew into a panic when she thought someone had made off with her one-of-a-kind Givenchy jacket at the Prada Met Ball after-party. Witnesses said that after arriving at the party at the Ukrainian Institute, “She was in a panic, saying someone stole my…Givenchy jacket.”

The witness said Tyler turned to masseur Lino Pastrana (who has worked with fashion leaders including Donna Karan, Donatella Versace and Riccardo Tisci), who crawled under a table and found the Givenchy jacket, much to Tyler’s relief. Also at the bash were Jessica Biel and Justin Timberlake, Jessica Alba, Mick Jagger, Florence Welch, Ashley Greene, Camilla Belle and Mario Testino. Tyler’s rep didn’t get back to us.
