Guests celebrating the New Year at the Esperanza beach resort in Los Cabos, Mexico were treated to an extra special night when newlywed JOSH KELLEY and newly-engaged FERGIE performed an unplanned duet.

The pair was holidaying with partners Katherine Heigl and Josh Duhamel when they took to a makeshift stage near the hotel’s outside bar on New Year’s Eve (31Dec07).

Kelley tells America’s Life & Style magazine, "Me and Fergie got up and did a duet together… Santeria by Sublime. It was fun." And there was a further treat in store for those who caught the impromptu performance - Kelley agreed to burn copies of his new album, Special Company, for anyone who asked to hear more of his music.

The album hits the iTunes.com website as a download next week (beg14Jan08).

It hits stores on 5 February (08).
