The Black Eyed Peas canceled a concert in San Salvador after Fergie fell ill.

The daily newspaper La Prensa Grafica reported that some 10,000 people were at the concert Friday when the 32-year-old singer suddenly told the crowd she was sick. The show was canceled minutes later.

The band was in Mexico and Central America as part of their "Monkey Business" tour.

Two Show, the concert's organizer, said in a statement Monday that it plans to reschedule the concert sometime within the next three months. It also offered refunds to dissatisfied fans.

The statement didn't say why the show was canceled, and Two Show didn't return calls seeking comment.
