The singer, who plays her final UK date at London's Wembley Arena tomorrow (09.04), also said she is happy her fans are able to personally relate to her songs.
'Sometimes I see all kinds of emotions, it's a lot of emotion,' she told MTV News.
'It's lovely, too, because I love people that are passionate about life and music in general,' she continued.
'That's why I write a lot of times - to continue to evolve as a person, and I can see the same thing has happened with other people; they've just adopted the song for themselves.'
