During an interview with Cosmopolitan for its April 2015 issue, the singer admitted that her 2014 song, "All About You," was written "for a reason."
"You could be my dirty secret/I could be yours," the song goes. "We could only be a rumor/Never be sure, you could meet me in the backseat/Late night, a ticket up in first class/Mile high."
Duff revealed the song was indeed written from personal experience. "I think everyone should have something where you know it's not exactly what you're looking for but you just have a wicked good time. That was really freeing for me and a bit of an awakening. It's fun to have a secret."
Of course, Duff also opened up about the heartbreak in her past, as well.
"I had a pretty serious relationship at a young age that I ended, and it wrecked me for a good year and a half," Duff shared. "I didn't really enjoy being single." The magazine also asked her when she lost her virginity, to which she replied, "I had a 26-year-old boyfriend. So everyone can make their own assumptions about what I was doing."
Though she didn't name names, many are speculating that she's talking about Joel Madden, whom she dated when she was just 16 and he was 25.
Following their breakup, Duff went on to marry Mike Comrie, from whom she separated just last year. Though the couple tried to make it work, the two are now officially going through divorce proceedings. Duff and Comrie have one son together named Luca.
