There's a special autograph signing on Saturday May 23rd in San Jose, CA featuring Tarah Paige from Transformers: Revenge of the Fallen. Possibly hinting at a new character?

To whom it may concern I just wanted to let you know that this weekend we are having one of the cast from Transformers: ROTF signing at our show from 11am-4pm. The actress is Tarah Paige. Without wanting to reveal any spoilers here rumor has it she is playing a key role in the new movie that has been kept hush hush. What is out there is that she is potentially Sam's new love interest in the movie. You can download a PDF version of the flyer for the signing here or visit our show website for more info. We appreciate your help spreading the word so all Transformers fans have a chance to come out and meet her. We also have several vendors with many new, hard to find and vintage transformer toys. Admission & Parking are always free.

Someone looks like Carly! Tarah Paige

Well, at least that's who she could be.

 

She could be voicing Arcee. That seems plausible.

 

might be a stunt double? she did alot...

one of the drivers of the 3 arcee bikes?

 

She might be Isabel Lucas' stunt double or a whole new character perhaps...

I put myself forward as the only individual hoping both are true.
