Actress has hit the dye
Sienna Miller is rocking a red hot new look.
Tom Sturridge‘s fiancée left her long locks loose before piling them into a bun to paddle in the sea with the pair’s daughter Marlowe, 1.
As well as showing off her copper tone, Sienna displayed her slim post-baby body in a tiny black bikini.
The 32-year-old – who usually sports glossy golden highlights – accessorised her sexy string swimwear with dark shades.
