Margot Robbie is the hottest girl in Hollywood these days. The 23-year-old Australian actress who played the role of a trophy wife to Leonardo Di Caprio in the super hit award winning movie "Wolf of Wall Street" has been famous for her beautiful blonde hair. But the "Duchess" (the name of her character in the movie) has ditched her bombshell blonde locks and has dyed her hair brown. The social media is reacting to the news in a not so great way. Let's find out the reactions.

Margot took to Twitter to let the audience know about her new look by sharing her not so glamorous picture with her fans. "First day on set for Z! She ain't a Duchess no more," wrote Margot on Twitter with the picture of her wearing a baseball cap and no make-up.

Margot's fans who were used to seeing the actress in a glamorous avatar and complete make-up look were shocked to see the actress with brown hair and sans any makeup.

"The good news: Wolf of Wall Street's extended cut will be on the blu-ray. The bad news: Margot Robbie is a brunette now. :'(," writes Ron Taylor on Twitter after seeing Margot's picture.

"Switch back to blode look, super quick," writes Mellisa on Twitter, expressing her displeasure with Margot's new look.

"Ooh Margot Robbie has gone brunette! Thoughts?," wrote the Daily Mail on Twitter.

"MargotRobbie Oh no. You dyed your hair brunette," says Sir Juice on Twitter.

"@MargotRobbie: I'm now officially a brunette and spent the day milking cows and driving tractors!" @ashtothelay Damn she went brunette," said Cade mcgown on Twitter.

There are hardly any fans of Margot Robbie's new looks but let's not forget that the actress has just dyed her hair brown for a new movie "Z for Zachariah," which is based on the book by Robert C. O'Brien and co-stars Chris Pine and Chiwetel Ejiofor. Margot plays the role of a 16-year-old in the film who survives a nuclear war, hence the baseball look. The shooting of the movie has reportedly commenced in New Zealand. What are your views of Margot Robbie's new brunette hair? Do let us know your views.
