Iglesias representative Gary Mantoosh said later in a statement to The Associated Press his client and Spears won't tour "despite initial reports based on formal discussions of the possible run."
The statement says Iglesias "is very sorry for the confusion this might have caused to anyone." It says the Latin singer respects Spears and is a fan of her work.
Igelesias is on tour in Europe.
Spears on Tuesday released her seventh album, "Femme Fatale." Her U.S. tour kicks off June 17 in Sacramento, Calif.
A representative for the pop singer hasn't returned an email seeking comment.
