Kathryn Hahn: Her Day With May

What a workout! Kathryn Hahn gets her arms in shape while carrying 2-year-old daughter May as well as a toy stroller while running errands in Beverly Hills, Calif. on Friday (February 10).

The 37-year-old actress, who is best known for her role on Crossing Jordan, will soon start a multi-episode run on NBC's Parks And Recreation, playing a campaign advisor to Paul Rudd's character Bobby Newport.

Kathryn – who also has a son Leonard, 5, with hubby Ethan Sandler – was asked last year if she was thinking about expanding her family. "We have one of each so it's like why ruin a good thing, but who knows," she said. "It happens so fast. I miss it already."
