It would be the first time the rappers include Diddy and Brown on a disc, though they have previously worked with Iglesias and Martin.
The Spanish crooner worked with the duo on the songs "Lloro por Ti" (I Cry for You), "Gracias a Ti" (Thank You) and "No Me Digas que No" (Don't Tell Me No), while the duo joined Puerto Rican compatriot Martin for "Frio" (Cold) a cut on his new album.
"What we do is take giant steps. We try to do something different," Wisin said in an interview with Efe.
For his part, Yandel said they are eager to work with Diddy, Brown, Iglesias and Martin because "they are well-known names in music" and have given the duo a great deal of help with their career.
At a press conference Tuesday the reggaeton duo were presented as the new spokesmen for Doritos, an occasion that the artists used to talk about the grand finale of their tour "Los Vaqueros...El Regreso" (The Cowboys...The Return) on Dec. 3 at San Juan's Jose M. Agrelot Coliseum.
Wisin said that it was "too soon" to announce the international and local artists who will be in the concert, though they confirmed that members of their company, WY Records, would be there, and others who have followed their careers.
The rappers also said they are willing to work with the Puerto Rican govenment to launch campaigns against the crime and insecurity so prevalent on the Caribbean island.
