Thanks go to scooper BOBB for the tip he found at Transformerslive.blogspot.com. Here's what it says...
I received a tip from "Gwen" that says that Nina Dobrev (Degrassi: The Next Generation) has been cast in TF II for a role as a university student. Who, what, when, etc not known. I assume this means she will join Shia LaBeouf, Megan Fox, and Aaron Hill at the University of Pennsylvania when shooting starts there at mid-month. I am not familiar with the actress but a Google search show a very attractive 19 year old.
