And we just wish we looked as effortlessly cool as she does in her casual get up!
Keeping her look plain and simple, Amanda teamed her light skinny jeans with a pair of grey Converses. And choosing to go au naturel for her travels, the 28-year-old wore minimal make-up and let her long blonde locks fall past her shoulders.
Making sure she had all her travelling essentials to hand, Amanda accessorised her outfit with a floral printed bag slung over her shoulders.
The Mean Girls and Mamma Mia actress, known for being a dog lover, showed her support for her furry friends by wearing a slogan tee. Still managing to look stylish whilst doing so, she tucked her t-shirt into her skinnys.
Emblazoned with the words 'Save Them All', Amanda's tee is in aid of the Best Friends Animal Society - an American animal sanctuary for homeless pets.
And judging by her very cute snaps she has shared on Instagram of her beloved dog Flinn, Amanda clearly holds the charity and it's cause close to her heart.
For the bonde beauty, dogs are really man's best friend and Amanda sure knows how to have a lot of fun with her own. Together, the star and her pet pooch companion have posed up a storm from modelling shots, to imitating each other and catching each other mid laugh on camera.
