U2 singer Bono is a father again. Bono’s wife Ali gave birth Monday morning to a baby boy. The child is the couple’s fourth, following two daughters, Jordan, 11, and Eve, 9, and son Elijah, 21 months old, Reuters reported. The boy, who is not yet named, weighed 7 pounds, 7 ounces at birth. Bono, named Paul Hewson at birth, left U2’s North American tour to be with his family, and expects to rejoin the tour Thursday.
