Wepa", the new single by singer Gloria Estefan, goes on sale for digital downloading next Sunday from the iTunes virtual music store, the artist said Friday on her Twitter account.

The song will be available both in English and Spanish, as well as in four different remixes, and will be a first taste of her 11th studio album and the first in English since 2004's "Unwrapped."

The seven-time Grammy winner is finishing off the details of the upcoming album with the aid of rapper and producer Pharrell, who has worked with many other top stars including Madonna, Shakira and Jennifer Lopez.

"We're working on something really good," Estefan told blogger Perez Hilton about the new album.
