Heather Mills taught her and Sir Paul McCartney's daughter how to play the saxophone because the Beatles legend ''can't read music''.

Although Paul, 73, is one of the most revered musicians of all time, Heather - his former wife - says that she was responsible for showing Beatrice, who was born in 2003, how to play the instrument.

She told The Guardian: ''I think she's got the best of both of us, we're both very musical. I taught her the saxophone, because her father can't read music so I do all the music teaching, and I'm good with languages. She's a brilliant poet so obviously gets that from him, but I think she's got the best of both of us.''

Paul and Heather married in 2002 and divorced acrimoniously in 2008 and Heather - who was married to Alfie Karmal in 1989 for two years - admitted she has nothing nice to say about her second husband.

She said: ''I don't want to go into my second marriage too much because if you haven't got something nice to say about someone you shouldn't say anything at all, and it had a lot to do with the person I married.'

Music legend Paul - who gained worldwide fame as the bassist of British rock band the Beatles - went on to marry Nancy Shevell in 2011.
