It's a boy for Molly Sims! The 39-year-old model and her husband, producer Scott Stuber, welcomed their first child yesterday. The little one weighed in at a little over seven pounds, and his name is yet to be revealed. “We’re still not decided on the name, my husband and I are going back and forth,” Sims told last month at the Liz Lange Maternity for Target anniversary party in New York City.But they were working on it! "We’ve got charts and diagrams." Congratulations to the new parents.
