"Law & Order: SVU" star Kelli Giddish is a mother of two. The 38-year-old actress welcomed her second child with her husband, Lawrence Faulborn, this week. The couple are also parents to 3-year-old son Ludo. Faulborn announced the news in an Instagram post Tuesday. He posted a close-up photo of the infant's feet but did not share the baby's name or sex. "#thefamilyjustgottwofeetbigger," Faulborn wrote. "Law & Order: SVU" showrunner Michael Chernuchin was among those to congratulate the couple online. "Mazel Tov @KelliGiddish," the producer tweeted Wednesday. Giddish announced her pregnancy in September by debuting her baby bump at the "Law & Order: SVU" Season 20 premiere. She told E! News her pregnancy would be written into the show. Giddish's co-star Mariska Hargitay shared a photo last week of the actress baring her baby bump. "#MyViewRightNow #Beauty #Life #FullOfLife #FullOfLove #CoStarLove #Mama #Love #BabyLove #BundleOfJoy #BabyOnTheWay #BabyGoals #ComingThisFall #SBU #SpecialBabyUnit," she wrote in the caption. Giddish and Hargitay play Olivia Benson and Amanda Rollins on "Law & Order: SVU." The series premiered its 20th season on NBC in September.
