TONI Collette has revealed her dramatic new ‘do, shaving off her long blonde locks for an upcoming film role.

The 41-year-old actress debuted the bold buzz cut at a charity event with co-star Drew Barrymore in London overnight.

Collette plays a cancer victim in her new movie Miss You Already, which tells the story of two girlfriends whose friendship is put to the test when one falls ill.

Barrymore replaced British actress Rachel Weisz to land the role of Jess in the Catherine Hardwicke-directed film.

Collette stars as best friend Milly, whose life is upturned when she is diagnosed with cancer.

The Aussie star teamed her edgy cut with an equally edgy ensemble, donning a black leather jacket, black jeans and plenty of gold necklaces.

Miss You Already is scheduled for release in 2015.
