Nicole Richie And Daughter Harlow Stay Active

Nicole Richie is staying fit through her second pregnancy-and keeping daughter Harlow, 17 months, active too.

The mom-to-be and her daughter shared a playdate at the children's gym Fit For Kids in West Hollywood.

"They were having a lot of fun playing in the ball pit together," says an onlooker."They were having a great time running and jumping around."
