Coco Rocha took six months to cut her hair.

The Canadian supermodel - who chopped her long locks into a chic pixie bob last week, showing off the shocking change on Instagram - admits it took her almost half a year to be able to execute the new look because she had to ask the big bosses in the fashion industry for their permission first.

Speaking to E! News, she said: ''I've been trying to cut my hair for the past six months weirdly enough. You'd think that would be easy to do, but in my profession, supposedly you have to ask everyone for permission! So finally I have cut my hair.''

However, the 24-year-old star is grateful for the wait because it gave her time to decide whether she really wanted to carry out the drastic change, and she's now adamant she'll never allow it to grow back.

She explained: ''I think I honestly needed that time to think because one day I'd be like, 'Yeah I'll cut it,' and the next day will probably regret.

''But today I am still happy with it, I have no regrets, I love it, it will probably never grow back. It's the best feeling ever.''
