Jordin Sparks has been ordered to rest her voice due to a reported acute vocal cord hemorrhage that could cause permanent damage to her vocal cord. "Jordin Sparks is on vocal rest and is expected to make a full and complete recovery," according to a statement from her record label. "Sparks has been going nonstop over the past two years and now she's going through the normal course of learning how to manage and care for her voice."

The 2007 "American Idol" winner will miss all April concert dates on Alicia Keys' tour, which kicked off Saturday in Hampton, Va. Sparks also canceled a scheduled appearance last week on the "Live With Regis and Kelly Show" and a special Earth Day performance at Washington, D.C.'s National Mall. The 18-year-old singer is set to return to Keys' jaunt in May. Read the full story.
