Emma Watson has been showing off a new hairstyle at the Spanish premiere of her new film, Regression.

The 25-year-old actress clipped her hair back, but had it loose and longer at the front as she hit the red carpet at the Villamagna Hotel in Madrid.

The former Harry Potter star, who looked stunning in a black top and statement skirt by Christopher Kane and custom-made heels by Paul Andrew, was joined by the thriller’s director and writer Alejandro Amenabar at the screening.

Emma plays a young woman who accuses her father (David Dencik) of an unspeakable crime in Regression, which also stars Ethan Hawke and David Thewlis and opens in UK cinemas on October 9.

Emma is no stranger to changing up her hairstyles.
