Work hard, play hard! Kristen Stewart was spotted filming scenes for her upcoming drama Still Alice with costar Julianne Moore on Long Island's chilly Lido Beach Friday, March 21. The night before, the 23-year-old actress ate dinner in New York City with her dad, John Stewart

Braving the cold weather, Stewart simles while strolling with Moore, 53, on a boardwalk. In the Richard Glatzer and Wash Westmoreland-directed film, Moore plays a professor who is diagnosed with early onset Alzheimer's disease. Stewart plays her daughter.

The Twilight star appeared to be in good spirits while filming Friday -- no evidence of a hangover in sight! The evening before, Stewart went to dinner with her dad and another pal at Beauty & Essex in NYC's Lower East Side. A source tells Us Weekly that Stewart dressed casually in a T-shirt, jeans, and glasses, and arrived at around 9 p.m. The group dined on Beauty & Essex specialties such as grilled cheese and tomato soup dumplings, and the signature Masterly Touch cocktail.

The insider adds that Stewart later asked her waiter for a spicy vodka drink instead, and a mixologist created a cocktail with vodka, muddled cucumber, jalapenos, lime, simple syrup and a splash of Grand Marnier. "The newly concocted beverage was a hit with Stewart," the source says, "and she drank a few of them!"
