Hilary Duff had little Luca Comrie on her hip to run errands in LA yesterday. Afternoon outings are regular occurrences for Hilary and her son. Last week, Hilary took Luca to a Babies First Class session before a shopping trip together. Between the many outings, Hilary has also been focused on getting back into shape after giving birth to Luca back in March. It appears that all of her hard work at the gym has paid off. Hilary shared a snap of her size 26 skinny jeans and thanked her trainer, Gabe Johns, for his help just a few days ago.
