A Mr Frost already reported, Alicia Keys will tour the US starting April 19th. It was just announced today that American Idol winner Jordin Sparks will support Keys on the upcoming tour. Sparks was named Outstanding New Artist at the NAACP Image Awards, the same award ceremony where Keys won four awards including Outstanding Female Artist and Outstanding Album. It would seem a smart match for the two to deliver their different styles of RnB to fans across the nation.
