(Cover) - EN Showbiz - Kimberly Stewart's baby daughter Delilah has been given a star-powered name.

The one-month-old tot will have her mother's last name as well as well as that of her father, actor Benicio Del Toro.

There was much speculation over whose name the child would have because Kimberly and Benicio had a short-lived romance and were never in a committed relationship.

But TMZ has published the birth certificate of the baby which shows she is registered as Delilah Stewart Del Toro.

Kimberly, 32, is the daughter of rocker Rod Stewart who has eight children of his own, the youngest of which was just born in February of this year.

The sometime model is said to want to have a relationship with the Benicio, who won an Oscar in 2001 for his role in Traffic, but he is reportedly too busy for a girlfriend.

The duo were only seeing each other casually for a month before Kimberly became pregnant much to everyone's surprise.

"Benicio is the father and very supportive," his spokesperson said back in April before making clear that the actor was not committed to Kimberly.

"Although [he and Kimberly] are not a couple, they are looking forward to the arrival of the baby." (C) Cover Media
