Andrea Riseborough debuted a shockingly short new haircut at a Gala screening of Matilda The Musical in London on Monday. 

The actress, 41, swapped her long locks for a shaved head as she joined her co-stars at the swanky event at Curzon cinema in Mayfair.

Andrea, who plays Mrs Wormwood in the flick, looked gorgeous in a ruched black gown which she teamed with a matching cape.  

The quirky dress hugged every inch of her incredible figure and completed the look with a pair of emerald green boots.

Andrea, who sported her long hair in tight braids at Amsterdam’s London premiere September 21, proudly showed off her new look. 

The British star accentuated her features with a dewey make-up look featuring a lashings of metallic eye shadow and a chic nude lip.
