Break out the pink balloons! "Freaks and Geeks" actress Linda Cardellini and her boyfriend Steve Rodriguez welcomed their first child, a daughter named Lilah-Rose, on February 29, her rep confirms to Us Weekly.
Also known for her roles on "ER" and as Velma in the "Scooby-Doo" film franchise, Cardellini, 36, confirmed her pregnancy in October 2011.
Dealing with a nasty bout of morning sickness for the first four months of her pregnancy, the actress has called impending motherhood a "miracle."
"It's amazing and I can feel kicking and it's a totally unbelievable experience," she told Access Hollywood last December. "It's a little bit like 'Alien' in science fiction and then also it's a crazy miracle."
