Kimberly Stewart is a mom! Rod Stewart's daughter gave birth to a little girl on Sunday in Los Angeles. The new baby was 22 inches long and weighted 8 pounds, 9 ounces, and the name has not yet been revealed.

This is the first child for both Kimberly and Oscar-winning actor Benicio del Toro. "Benicio is the father and is very supportive," his rep said back in April. "Although they are not a couple, they are looking forward to the arrival of the baby."

The bundle of joy came one day after Rod Stewart hosted a large birthday party for her at Dan Tana's in LA.

Congratulations to the new proud parents!
