Rather than keeping her sweats and trainers on post-workout, the gorgeous star slipped into a cute black jumper, patterned skirt and black tights as she walked to her car.
Dakota's gearing up for the release of Fifty Shades next month, which will no doubt catapult her to international celebrity alongside co-star Jamie Dornan.
She recently told Vogue that the idea of becoming famous was rather scary but she couldn't have turned down the chance to be part of Fifty Shades.
"It's just the most insane thing to be part of. I've never experienced anything like this; I don't think anyone has. It's terrifying and it's exciting," she said.
"I think about my dwindling anonymity and that's really scary because a very large part of me would be perfectly happy living on a ranch in Colorado and having babies and chickens and horses – which I will do anyway."
Fifty Shades of Grey is based on the erotic novel by E.L. James documenting the relationship between naïve Ana (Dakota) and billionaire businessman Christian (Jamie).
It arrives in cinemas on Valentine's Day.
