Bumblebee, Shia LaBeouf Spotted Cheating on Megan Fox on Transformers 2 SetS

Flickr photographer Zacklur got a shock a couple of days ago when he woke up to find Michael Bay filming a scene from Transformers: Revenge Of The Fallen outside his bedroom window. An even bigger surprise was seeing Isabel Lucas (of Home and Away fame) riding in the passenger seat of the 2010 Chevy Camaro SS instead of Megan Fox.

According to Zacklur, the scene being filmed showed the yellow Camaro spinning out shortly before Isabel gets covered with "green goo," then storms off. Could this be Bumblebee trying to tell Shia something?
