Kimberly Stewart and stepmom Penny Lancaster get into the Halloween spirit early as they take their children to a costume party

It's only a matter of time before trick-or-treaters will begin scrambling to select the perfect Halloween costume for this year's festivities. But fortunately Kimberly Stewart's wise little girl Delilah will not be among them.

The sweet little three-year-old was seen clad in a darling owl costume as she was guided by her 35-year-old mother to a Halloween party in Studio City on Saturday.

Delilah - whose father is actor Benecio Del Toro - looked absolutely precious in her soft grey owl outfit complete with a matching cape.

Her grey cape featured a fluffy powder pink trim, which paired nicely with her white leggings. Polishing off the dear outfit were a pair of well-worn ballet shoes.

Delilah's mother, meanwhile, kept warm in a soft black sweater that loosely hung upon her arms.  She teamed the top with a pair of grey jeans that showed off her toned pins to full effect, and polished off the low-key look with a pair of edgy ankle boots.

Kimberly looked relaxed as her sunny blonde locks tumbled down upon her shoulders. The daughter of rock star Rod Stewart ensured her little one stayed close by with a hand gently placed upon her back.

Meanwhile, Kimberly and her daughter weren't the only members of the Stewart family in attendance at the party.  Her father's wife, Penny Lancaster, was also seen with her and Rod's three-year-old son Aiden, who donned a Dracula-themed outfit.

Penny was seen browsing through a table full of treats as her little boy stood close by.
