Kisses for baby Luca! Hilary Duff and her sister, Haylie Duff, took Hilary's adorable son Luca, 11 months, for a swim on Wednesday, March 6.
The sisters, both wearing swimsuits with their hair pulled up, posed for a picture together in the water. Haylie cradled her nephew and they both showered him with kisses.
Though he's probably still learning how to swim, little Luca has recently learned how to walk.
"Well, I officially have a walking baby on my hands!" Hilary announced on Twitter Feb. 28 of her son with husband Mike Comrie. "It's hilarious . . . the wobble makes it look like he's 3 drinks in!"
