Adele has reportedly been asked to sing the next James Bond theme song. Bosses of the spy franchise are so impressed with the Oscar winning theme to Skyfall - written and recorded by Adele with producer Paul Epworth - they want her to work on the next instalment when it goes into production.

"Producers are thrilled by how well the song has been received and hope Adele's presence on the next film will replicate that success. They want her to become as synonymous with Bond as Shirley [Bassey]," a source said.

The huge-voiced Welsh singer Shirley sang the themes to three James Bond films: Goldfinger in 1964, Diamonds Are Forever in 1972 and 1979's Moonraker, three of the most loved from the series' 50 year run. However, Skyfall is the most awarded and successful Bond theme of all time, selling over three million copies worldwide.

Fans are also keen to hear new songs from the star - whose 21 album has sold over 25 million copies since release in January 2011 - but is waiting for inspiration to hit.
