Funny, they don't look cold.

Sarah Jessica Parker, 45, and Pierce Brosnan, 57, took a carefree stroll on the set of their new romantic comedy, I Don't Know How She Does It, despite the 20 degree weather that plagued the New York City shoot on Tuesday. In a departure from his recent career as womanizing British spy James Bond, Brosnan is teaming up with the Sex in the City star in this love story based on a novel by Allison Pearson. In it, Parker will play Kate Reddy, a driven executive who supports her husband and kids.

Also slated to star in the romantic comedy, which just started production, are Kelsey Grammer, Christina Hendricks, Olivia Munn, Greg Kinnear, and Seth Meyers. —KIMBERLY STEELE
