In 1968 British stylist Vidal Sassoon was recognized for creating one of the most iconic haircuts of all time, the 'pixie cut'.

But almost five decades later Mia Farrow, the actress that rocked the do for career-defining role in Rosemary's Baby, has revealed that she was behind the urchin style.

In a letter to the New York Times Farrow said Sassoon had played no part in creating the pixie look and that she had taken scissors to her coif months earlier.

"I intend no disrespect to Mr. Sassoon, but he had nothing to do with my haircut," she said.

"I had literally cut it myself earlier that year - with a pair of fingernail scissors - while working on the Peyton Place TV series at Fox Studios.

The 67-year-old actress continued: "This was long before I ever heard of Vidal Sassoon. My then-boyfriend, Frank Sinatra, loved the cut, and so I kept it short. (I purchased some hair scissors; then, as now, I cut it myself.)

"Vidal Sassoon is mentioned in the book 'Rosemary's Baby' and the film. So, Paramount decided to stage a photo shoot in which Mr Sassoon trimmed my 1 1/2-inch hair to 1 inch. The whole event was taken in good spirits. (I wore a wig during the earlier scenes.)"

Farrow was keen to set the record straight after the New York Times newspaper ran a feature about career-changing haircuts.

The publication had insisted that Farrow sported long, blonde hair until Sassoon gave her the pixie cut for Roman Polanski's horror film.

Even till today, the pixie cut is still a hit with stars including Emma Watson, Victoria Beckham and Anne Hathaway trying out the closely cropped coif.

Farrow also added that claims that her husband at the time, Frank Sinatra, divorced her because of the boyish look were also false.

"Neither, I can assure you, did my divorce from Frank Sinatra have to do with my haircut."
