Dido admits she once shoplifted from a chemist when she was in a hurry to catch a train.
The singer says she also walked out of a hotel with an ironing board to use on her tour bus.
In an interview with Sister Bliss from Faithless, she also confesses to dabbling with drugs.
Dido told Mixmag: "I wasn't really into the whole drug scene. I'd tried things and not really liked them.
"I used to be out clubbing nearly every weekend a few years ago but when the fashion in music changed to being more rhythmic then song-led I'd still go and have a dance but I got bored very quickly."
When asked if she had ever broken the law, she said: "I once shoplifted a lipstick from Boots. The queue was really long and the till people were being really dumb. And I had a train to catch.
"Does taking an ironing board from a hotel count? I walked straight out with it and pillows too. I had my reasons. The pillows on the tour bus were awful and the venue for that night didn't have an ironing board. It was practical."
Dido adds that at the start of her career she used to suffer from panic attacks, after witnessing a stabbing in the audience at a Faithless gig.
"It was a really nasty period," she says. "I couldn't do a thing. I'd try and then my heart would speed up. I'd be clammy and shaking at utterly in a state."
She says she eventually visited an acupuncturist to reduce her heart rate.
