Boybander Louis Tomlinson confirmed the news Saturday morning on Twitter that his baby son was born in Los Angeles. The mother is Briana Jungwirth, an L.A.-based stylist with whom Tomlinson was briefly romantically-involved last May. Thomlinson wrote, "I?m pleased to say my baby son was born yesterday. He is healthy and pretty amazing." The child is the first for the 24-year-old British singer, as well as the first for any member of his band, One Direction.
