Fox News’ Peter Doocy and Hillary Vaughn Welcome Baby Number Three, a Girl Named Molly Kate Peter Doocy and his wife, Hillary Vaughn, are now a “party of five.” The couple welcomed their third baby, a daughter named Molly Kate, on Oct. 22. She joins big siblings Bridget, 3, and George, 18 months. Peter, 39, says Hillary called him just one minute before anchors tossed to him for a 9 a.m. live shot that day. He told PEOPLE, “I don’t think I’ve ever talked through a script so fast.” Then he grabbed his bag and sprinted toward the White House gate. Molly Kate arrived at 10:04 p.m. Hillary, 37, says the couple’s “hearts are bursting with joy.” Peter says the house “felt ten times more full” when they brought the baby home. He also joked that she arrived “a few days after the due date,” but just in time for Midterm election results. Hillary says the first meeting with her siblings was “quintessential toddlerhood.” George cried at the sight of his baby sister. Then Molly Kate cried. Bridget was on the brink of joining in. Hillary says George has since embraced being a big brother. She says Bridget “can’t wait to share her extensive bow collection” with the baby. Peter and Hillary met while working at Fox News and married in South Carolina in April 2021. Bridget was born in February 2023, and George followed in April 2025.
