18-year-old singer and American Idol winner, Jordin Sparks, has suffered some vocal problems that lead her to withdraw from all of her performances scheduled for the rest of April.

Of these are her scheduled openings for the beginning of Alicia Keys' tour and a performance in Washington D.C. at the Earth Day Network and Green Apple Festival. Sparks is set to get back to performing in May, joining Keys after the first month of the tour.

She is expected to fully recover after her vocal rest.
