For her transatlantic flight Rosie rocked a pair of Burberry jeans, a leather jacket and a large, cozy patterned scarf. Personally I think the bag and scarf are the best parts of Rosie's outfit; the bag is so perfectly worn in, and the scarf adds a bit of pizazz to the otherwise basic-ness of the jeans and neutral flats.
On a side note, how gorgeous is this girl? When I heard they were going to be replacing Megan Fox for the final Transformers film, I must admit, I was a little skeptical based on Megan's hotness. Looks like they found her match in Rosie, though. I'm so excited for Transformers Dark Side of the Moon, are you?
