Taylor Hanson's Wife Expecting Baby Number 4

Former boy band star Taylor Hanson is about to be a father of four, People Magazine reported. Hanson's wife, Natalie, 26, is due this winter. It seems like just yesterday that three teenage boys took the music industry by storm, but in recent years their swooning female fans have had plenty to cry about. Isaac, Taylor, and Zac Hanson are all off the market - married, with children. Isaac, 27, is the father of two sons; the youngest, James Monroe, was born on July 11. In May 2008, Zac, 22, become a first-time father, when his wife, Kate, gave birth to son John Ira Shepherd. In November 2007, Zac told People that he looked forward to watching a new generation of Hansons grow up together because "watching them is going to inspire a lot of music." He may have been right. According to People, the Hanson brothers begin touring this fall to promote their new album, The Walk. The Walk Around the World Tour is intended to raise money to fight African poverty. Portions of the album were recorded in Africa, and at least one track features the voices of children from Mozambique and South Africa, People reported. In an interview with the magazine, Zac Hanson confessed that having a child had made him more sensitive toward the struggles on that continent. "When you look at what AIDS is doing to families over there and think about how our little son is never going to deal with those kinds of struggles," he said, "it helps you realize how important it is to give these people the ability to help themselves."
