Sir Paul McCartney's five-year-old daughter appears on his new album.

Beatrice - Paul's daughter with ex-wife Heather Mills - appears on the track 'Two Magpies' from Paul's latest LP 'Electric Arguments' with his side project The Fireman.

A source told Britain's Daily Mirror newspaper: "Beatrice was in the studio and during the recording of 'Two Magpies' she grabbed some earphones and said, 'I want to play the piano', which was picked up on the microphone.

"When Paul played it back he thought it sounded really cute and insisted it be left in the final version.

"Pals say if he releases it as a single, it should be listed as Sir Paul McCartney featuring baby Bea."

It seems Beatrice's music career is taking off. Last week, it was revealed Paul, 66, is planning to include her on backing vocals in a new track he is writing for the next 'Shrek' movie.

A source said: "Paul is really pleased to be part of the next 'Shrek' film because it's Beatrice's favourite. He wants to go one step further though and make sure she's part of the film.

"Paul's writing a song for the film and wants Beatrice to sing some of the harmonies. She's quite a musical kid. It will be a dream come true for her."

'Electric Arguments' by The Fireman - which is a collaboration between Paul and music producer Youth - was released yesterday (17.11.08)
