This week in New York, Katie Holmes and Blake Lively went to the ballet. The two were photographed together at the American Ballet Theatre’s annual spring gala, each wearing bright strapless gowns. They joined guests to watch choreographer Alexei Ratmansky’s ballet Whipped Cream, a story of a boy eating (and dancing) his way through a Viennese pastry shop.
Elsewhere, Mary J. Blige performed at the Valentino cruise show after-party at the top of the Standard Hotel. In Miami, Shakira threw a party for her new album El Dorado, out today.
