Hilary Duff took her 11-month-old son, Luca Comrie, to a Babies First Class in LA on Wednesday. She wore a loose tie-dye maxi dress, and he sported a "Hello, Ladies" shirt for the interactive mommy-and-me class, which the two have been regularly attending. While Hilary has been clocking in mom duty, she and husband Mike Comrie still find time to sneak away for couple's outings. They attended a Laker game last month and, more recently, the PGA Tour Wives Association 25th Anniversary event in Santa Monica, CA, on Monday. At the golf celebration, Hilary revealed that she's lost 30 pounds since giving birth to Luca in 2012. She credits the weight loss to a combination of circuit training and sculpting Pilates sessions.
