Liv Tyler is a mom for the second time! The actress and her boyfriend, sports agent David Gardner, welcomed a baby boy on Wednesday. Liv's rep confirmed the news in a statement, saying, "He's healthy and everyone is very happy." A source close to The Leftovers star tells People that the baby boy was six and a half weeks early and may need to stay in the hospital "for some time." This is the second child for Liv, who has a 10-year-old son, Milo, with her ex-husband, Royston Langdon. David also has a son from a previous marriage, 7-year-old Gray. Congrats to Liv and her family!
