Ricky Martin: Orginally due to perform at the ceremony

The Latin Academy of Recording Arts & Sciences subsequently decided that a lavish awards ceremony would no longer be appropriate.

Stars from the Latin music world are expected to attend the press conference, at the Conga Room nightclub near Hollywood, but no names have been announced apart from the Latin Recording Academy president Michael Greene and the Academy's senior vice-president Enrique Fernandez.

There will be no speeches or performances during the event, and artists will not be told who has won in advance.

Christina Aguilera has been nominated for two awards

Colombian rock artist Juanes heads the list of prospective winners with nominations in seven categories.

He is up against Spanish artist Alejandro Sanz, who received five nominations including best male pop vocal.
