Sarah Jessica Parker – who turned 48 on March 25 – took in a little performance art on Monday, when she and her husband, Matthew Broderick, stopped by New York's Museum of Modern Art to check out Tilda Swinton's piece, "The Maybe."
In "The Maybe," a surprise performance piece, Swinton sleeps in a glass box in front of museum goers.
Wearing a cream colored cardigan, her hair in loose waves and light colored jeans, Parker excitedly chatted with Broderick and two male friends as the We Need to Talk About Kevin actress laid comfortably in her box in front of a small crowd of onlookers.
Parker laughed with her husband – who was sporting round black glasses – and their friends as security guards kept museum goers from taking photographs of the snoozing Swinton.
