Shia LaBeouf and his costar Rosie Huntington-Whiteley were together on the Milwaukee set of Transformers 3 yesterday. Production was set up outside the city's art museum, and hundreds of gawkers came out to see the action. Shia and Rosie have been hard at work on the blockbuster for the past few months, filming action sequences and relaxing between takes. He had some downtime to meet up with friends, but his and Rosie's Summer has mostly been about their movie. Her first career, though, is as a model, as she's front and center in the Fall campaign for Loewe.
