Sarah Palin's son Track and his wife Britta welcomed a baby girl Sunday, a source confirms to Us Weekly.

A rep for the Palin family confirmed to Us in May that Track, 22, and his high school sweetheart, Britta, said "I do" in Hatcher Pass, Alaska. "Our families couldn't be happier," the bride and groom's families said in a joint statement. "These are two hard working, humble, active, studious young adults who grew up together. We're tickled that after two decades of friendship we proudly witnessed their marriage, knowing their new life together will be blessed."
