New hair do care! Malin Akerman reveals new dark hair colour on Rampage set with Jeffrey Dean Morgan

She's the ultimate blonde bombshell.

But Malin Akerman revealed a shock new look on the set of her latest movie. 

The 38-year-old actress revealed a dramatic chestnut hair colour as she filmed scenes for Rampage, in Atlanta, Georgia, on Thursday.

The Billions star looked transformed, as she carried off the colour change thanks to her stunning features. 

She had a side parting and no bangs, unlike her blonde style, so it's possible she was wearing a very convincing wig. 

She showcased her slim middle in high-waisted trousers with a tie-wrap.

Malin, who recently started dating British actor Jack Donnelly, has just had series Billions renewed on Showtime.  

The money-muddled drama only returned for its second season in February but has proven to be a big hit.

'Billions continues to be a show on the rise, growing not only in audience, but in critical buzz and cultural relevance,' Showtime president David Nevins said.

'It offers a unique mix of pure entertainment with sly commentary on our current have/have-not economy. Season 2 is off to a tremendous start, and has only whetted our audience’s appetite for what will come in Season 3.' 

The show debuted to record numbers for the network in January 2016, and continued to bring in average audiences of more than a million each week of its 12 episode run.
