Hello magazine cover altered to include photo of Del Toro

What a cutie! Kimberly Stewart, 32, has revealed her baby girl, Delilah, on the cover of the latest issue of Hello! magazine. The father is actor Benicio del Toro, 44.

Delilah, born August 21, is just over a month old. Though Kimberly and Benicio are not an item, she tells the mag he has been a very active dad, saying:

    "The whole family, including Benicio, was at the hospital and my mom and Benicio were in the delivery room with me. ... Benicio’s very involved; he and Delilah have a very special bond."

Kimberly also explains Delilah's name, and admits that she's got a bit of both mom and dad, Benicio (who is Puerto Rican) in her! Kim says:

    "I named her after the Tom Jones song, as I’d always loved that. ... Delilah is starting to smile; she’s the perfect little angel. She definitely looks like her dad, but she has my legs and eye color."
