Megan Fox
According to reports, "Transformers" director, Michael Bay, has replaced actress, Megan Fox, with Victoria Secret model, Rosie Huntington-Whitely.
Rosie Huntington-Whitely
The two worked together in December 2009, during a commercial for Victoria Secret, directed by Bay. She was allegedly recommended by director, Steven Spielberg, to fill in for Fox, who was fired.

The Judiciary Report does not think Rosie Huntington-Whitely is the right replacement for Fox. The cast of "Transformers" seem to be sad about the firing as well.
