Pair said to be teaming up again for unlikely duet
The pair have worked on Another Way To Die, the theme for new James Bond flick Quantum Of Solace.
And Alicia, 27, and White Stripes star Jack, 33, will certainly reach a different audience with the rumoured track.
Children’s TV character Postman Pat rose to fame in the 80s.
Quantum Of Solace is released next month.
