Singer Alanis Morissette and her husband Mario "Souleye" Treadway are celebrating the newest addition to their family this holiday season. According to "People" magazine, Morissette gave birth to a new baby boy, named Ever Imre Morissette-Treadway, on Christmas Day and the singer's rep says all are happy and healthy. Morissette and Treadway, a rapper, were married earlier this summer. The new baby will likely be her main project now, but Morissette did tell E!'s Chelsea Handler earlier this year that she is writing a book on philosophy and spirituality, among other topics. No word yet on when that book might be released.
