The actress Natalie Portman, who has an endorsement contract with Dior for its Miss Dior Cherie fragrance, has strongly condemned its chief designer, John Galliano, for anti-Semitic remarks after a video surfaced of Mr. Galliano appearing to deliver a tirade in a Paris bar. In a separate incident, he was accused of verbally abusing a French couple last week in the bar. He was suspended Friday from Dior.
