Rod Stewart’s daughter Kimberly and Benicio del Toro welcome a baby girl

It was a big surprise in April when reports said that Benicio Del Toro, 44, and Kimberly Stewart would soon be parents, as few knew they had a brief affair.

“Benicio is the father and very supportive,” the actor’s rep said. “Though [he and Kimberly] are not a couple, they are looking forward to the arrival of the baby.”

Alongside her father, Rod Stewart, her mother Alana Collins and her stepmother Penny Lancaster, the 31-year-old actress and model became a mother for the first time.

It is not known, however, if the father of the child was present during childbirth.

The child, whose name has not yet been revealed, is 22 inches long and weighs 8 lbs 9 oz.
