Watson, who starred in all eight Harry Potter films, made the decision to cut her hair after filming on the fantasy franchise ended.
The haircut was met with a mixed reaction, though it was recently voted one of the most influential hairstyles of last year.
"I had journalists asking me if this meant I was coming out, if I was a lesbian now," she told The Independent.
Of the change, Watson went on to say: "[It] did make me realise how subjective everyone's opinion is. Some people were crazy for it and some people just thought I'd lost my [mind]."
Watson has since decided to grow out the hair for future roles.
Emma Watson recently starred in My Week with Marilyn, and will next star in The Perks of Being a Wallflower alongside Logan Lerman.
