Hilary Duff kept up a busy schedule in LA yesterday. The actress began her morning with a boxing class in Hollywood, then changed out of her workout gear to go shopping in Santa Monica with baby Luca Comrie. Luca, 5 months, joined Hilary for their latest adventure as he adjusts to life with his first tooth. Her little man is used to hanging out with mom at home, but soon the pair might find themselves spending more time on sets. Hilary recently inked a new development deal that will have her producing and starring in an upcoming untitled TV series. No word on the concept, though it sounds like the half-hour comedy will likely play up the comedic timing she honed on her former Disney series, Lizzie McGuire.
