Madonna says she was left feeling ''a little bit depressed'' living in Lisbon because she was ''Billy no mates'' and spent most of her time transporting her teenage son to matches and school.
The 60-year-old singer, who relocated to the Portuguese capital in 2017 after her son David Banda, 13, signed for football club Benfica's youth academy, says the move spurred her on to create new music.
Speaking at an MTV Q&A in London on Wednesday night, she said: ''I didn't go to Lisbon to make a record, that was the last thing on my mind.
''My son wanted to be a professional soccer player so I kind of just spun the globe and did a lot of research for academies for boys to train and Lisbon ended up being my favourite city of the options.
''I went to Lisbon to be a soccer mom.
''I went there thinking it would be an adventure but I found myself just going to school and football matches.
''Really I was Billy no mates. I got a little bit depressed."
''And I thought I need to make friends and make friends.''

The Like a Prayer hitmaker managed to forge new friendships, and her new friends inspired her to make her forthcoming 14th studio album Madame X.
She added: ''I started to go out a bit and most of the people that I met were artists or musicians.
''I started getting invited to people's homes and I went to these living room sessions.
''People would drink wine and eat food and start playing instruments and singing.
''I was like, 'What's going on here?'
''Artists perform and they are doing it for fun and passion and don't get paid?''
Madame X, featuring guest appearances from Migos rapper Quavo and producer Diplo, will be released on June 14.
