Sienna Miller looks sultry with slicked-back hair in the Ford Mustang campaign.
The actress is a fashion favourite and starred alongside her fiancé Tom Sturridge in Burberry’s Fall/Winter 13 adverts.
Now she’s been tapped by the car company to promote its 2015 model.
As well as a video commercial, there are a series of sexy snaps showing Sienna posing in the slick red vehicle.
Sienna, 31, is usually known for her boho look, but instead wears a sexy black cut-out dress in the pictures.
In one, she leans back against the car as she throws the camera seductive look.
Her beauty look is just as sensual, with her blonde locks slicked back off her face to show off her razor-sharp cheekbones.
Although she’s known as a fashion fan, Sienna is also keen on cars.
“Every time I am in America I’ve always rented a Mustang to drive so I’m very excited it’s coming to Europe,” she gushed in a statement.
“It’s a completely iconic car and it’s beautiful in real life.”
Sienna proved her style credentials earlier this week when she wore an emerald green gown to the British Fashion Awards.
While she might look preened on the red carpet, the star admits she’s not always so on-point.
“Off-duty, it’s pretty gross, like tracksuits and T-shirts,” she confessed to Elle.com.
“But I guess I tend to really switch it up. I love rock ‘n’ roll stuff, I love tailoring – it’s kind of like a lot of different things.”
