Christina Applegate carried her daughter, Sadie, out of a ballet class in Sherman Oaks, CA, yesterday. Sadie, who turned 1 in January, was decked out in her dance clothes and ballet slippers. The mother-daughter outing came during a break from Christina's busy filming schedule. She's in the middle of work on the second season of Up All Night, which returns on Sept. 20. We recently visited the Up All Night set to see Christina in action with her costars Maya Rudolph and Will Arnett. In addition to her small-screen role, Christina has another job on her plate. She recently helped launch FabKids, a subscription service for girls' clothing, that plans to expand into boys gear next year.
