Baby's day out! Jessica Alba shows off trim figure in slender skirt nearly one month after giving birth to son Hayes.

She gave birth to her son Hayes on New Year's Eve.
And Jessica Alba looked absolutely fantastic while out for an afternoon walk with the little boy in Los Angeles on Saturday afternoon.
The 36-year-old actress was in fine form as she showed off her post baby body in a slender black skirt as she pushed the stroller through the streets.
