Songstress and international pop star Katy Perry has revealed that she used to take her guitar downtown in Santa Barbara, where she grew up, and find a place to play to the public as they went about their lives. 

Talking to GQ magazine about when she first realised she could potentially make money from her voice, she explained that at just 13-years-old she would busk for money:

"I'd go to the farmers’ market in Santa Barbara, and I’d put out my guitar case, and I’d test out these little ditty songs that I would write, and I would get a couple of avocados, a bag of pistachios, and, like, fifteen bucks. That was a lot of money for me.”

She added that her family really struggled financially and it was a tough environment to grow up in: We kind of barely got by... Money was always the biggest problem in our house.”
