The 56-year-old pop superstar - who has just released her new album 'Rebel Heart' - has admitted her turbulent romantic life has provided plenty of emotions and material to channel into her songs over the years.

Taking part in an Instagram Q&A (#askmadonna) with her fans on Tuesday night (10.03.15), she was asked "Where do you get the inspiration to write your songs?"

To which she replied: "By living. Just living (and dating the wrong men...) (sic)"

Madonna was previously married to film director Guy Ritchie - the father of her 14-year-old son Rocco - from 2002 to 2008 and was wed to actor Sean Penn for four years until 1989.

The 'Living for Love' singer has also previously dated Dennis Rodman, Warren Beatty, Jesus Luz and Carlos Leon - the father of her 18-year-old Lourdes.

During the online Q&A Madonna was also asked if she could remember the first words of her children and she quipped her eldest child Lourdes' first utterance was "no".

In response to the question, the star posted: "No is the first word my daughter said to me. And she's still saying it."
