LONDON -- Adele has confirmed she has co-written and performed the theme to the upcoming James Bond movie, "Skyfall."
The singer posted a picture on her Twitter feed Monday of what appears to be the sheet music cover page for the song, credited to Adele -- as A. Adkins -- and Paul Hepworth, who co-wrote her hit "Rolling in the Deep."
Rumors have swirled for months that the Grammy-winning British singer had recorded the theme, but there has been no official announcement from producers.
The film, Daniel Craig's third Bond adventure, opens in Britain Oct. 26 and in the U.S. Nov. 9. The cast includes Javier Bardem, Albert Finney, Ralph Fiennes and Naomie Harris.
The theme to the last Bond film, "Quantum of Solace," was performed by Jack White and Alicia Keys.
