Little Delilah's not so little anymore!

On Saturday, Kimberly Stewart and Benicio Del Toro were photographed leaving a pal's house in Los Angeles with some very precious cargo: Their daughter Delilah, who celebrated her first birthday last Tuesday Aug. 21.

Model Stewart, the 33-year-old daughter of rocker Rod Stewart, stayed casual in jeans, flowy black top and shades as she carried Delilah on her hip; scruffy, Oscar-nominated actor Del Toro, 45, wore his typical out-and-about gear of a graphic T-shirt and jeans.

Delilah, who was 8 lbs 9 oz. and 22 inches long at birth, is the first child for Stewart and Del Toro. Although the pair's romance subsided in early 2011, Del Toro was by Stewart's side when she gave birth, and he has vowed to play an active role in his daughter's life, according to a source.

As it happens, Delilah's rocker grandpa Stewart, 67, also became a father for the eighth time six months before she was born. The "Maggie May" singer's wife, Penny Lancaster, gave birth to their second son together, Aiden, in February 2011.
