Hilary Duff with her chiihuahua Lola, when both were younger than now. The Gossip Girl star is a complete tiny-dog nut and has a pack including, besides Lola and Lola's look-alike Coco, a dachshund named Chiquita, a chihuahua-terrier mix called Li'l Dog, pomeranians Macy and Griffin, yorkie named Jack, and a now deceased border collie named Remington. But Lola would appear to be her favorite (or perhaps just the best behaved) as she's the one most often seen around town with Hilary.
