After Sheryl adopted son Wyatt in 2007, she decided she wanted a second child -- but it wasn't so simple. For a year, plans to take home different babies kept falling through. Then, in June 2010, she announced that she had added son Levi to the family. Now her rocker lifestyle is much tamer. "My tour bus now is a family bus," she told New York Daily News in 2010. "I've got both my kids and everything that they count on to keep their lives normal on there, whereas before, my life was much more me-centric."
