Nothing says "summer has arrived" quite like a polo match! Non-Stop co-stars Julianne Moore (in Rosie Assoulin) and Lupita Nyong'o (in Alexander McQueen) posed with Olivia Munn (in Lover the Label) at the Veuve Clicquot Polo Classic, where celebrities and designers alike toasted the seventh annual event. "This is my first time," says Behati Prinsloo, who threw out the ceremonial ball toss before the start of the match between Team Veuve Clicquot and Team Black Watch (below). "I’ve never actually seen polo in person so I’m very excited to be here."
Busy Philipps, and more guests took a break from sipping champagne to stomp the divots with a scenic backdrop of the Statue of Liberty and the Manhattan skyline. "The kids have a play-date in the city today and we get to have champagne and chill by ourselves," Philipps tells InStyle.com. "We thought, let's go for a fun adult day date!"
