On 24 July 2007 "Billboard" magazine reported that Lopez and now ex-husband Marc Anthony would "co-headline" a worldwide tour called "Juntos en Concierto" starting in New Jersey on 29 September. Tickets went on sale 10 August. The tour was a mix of her current music, older tunes and Spanish music. In a later press release, Lopez announced a detailed itinerary. The tour launched 28 September 2007 at the Mark G. Etess Arena and ended on 7 November 2007 at the American Airlines Arena in Miami, Florida. The lead single, "Qué Hiciste," was officially released to radio stations in January 2007. Since then, it has peaked at 86 on the U.S. Billboard Hot 100 and number one on the Hot Latin Songs and the Hot Dance Club Play. It also went top ten on the European chart. The video for the song was the first Spanish-language video to peak at number one on MTV's Total Request Live daily countdown.
