3pdate: Fox and Bee on Set, Patrick Dempsy in?

{mosimage} A double update for TF3 today! First off are some new pics from Celebrity Magazine of starlet Megan Fox (aka Mikaela) chilling on set – next to what appears to be Bumblebee! Sadly, no view on whether or not he's a convertible. Check out their pics here! Next, a rumor comes in from Bol.com, a Brazil news site, that reports Grey's Anatomy star Patrick Dempsy will be playing a roll in TF3. TFW translators say his role will be 'darker' than the others – Dr. Arkeville, perhaps? Discuss the possibilities here!
