Who knows what happened Megan Fox and Transformers 3? We will probably never find out, and who cares anyway! Either way Michael Bay and co will have to find a replacement and according to Deadline, the search might be over. Rosie Huntington Whiteley will sign on the dotted line unless it all falls apart. I know, I know, I had no idea who she was either except she is / was a Victoria Secrets model and recently worked with Bay for his Victoria Secret advert! Anyway, she looks the part!
