The singer has been sporting a new bob of late, and now she has revealed the story behind the haircut.
She tells People.com, "I wanted to experiment and colour my own hair. That was one of the biggest mistakes of my life. I thought it was semi-permanent colour. It was permanent colour!
"I was packing up to leave for a red eye flight, and I thought that I’d have enough time to rinse it out 'cause I’ve kept semi-permanent colour on long before.
"I ended up keeping it in for almost two hours and the permanent colour ate all of my hair. My hair had grown down to, like, right where my shoulder hits, it was nice and healthy and thick. I went and reached for the back of my hair and it was all in my hand!
"So I went to my stylist the next day and said, 'So, my hair’s broken off, I need you to fix it'. He was like, 'How did this happen?' and then cut all my hair off and it just turned out really cute. I actually used Beyonce's hairstylist... and I love it."
