"He's like a motivational speaker," Shia explained. "Tyrese is the most consistent positive energy you've ever been around in your life -- even on the set. He and Rosie [Huntington-Whiteley] were like the cheerleaders for us.
"Me and [director Michael Bay] are emotional and aggressive and we go through our ruminations, and [Tyrese and Rosie] sort of are the consistency," he continued. "Josh [Duhamel] too, come to think of it. They're all really solid that way. It is a family!"
In related news, in addition to acting as a "cheerleader" with Tyrese for the "Transformers" crew, Rosie Huntington-Whiteley - a newcomer to the sci-fi robot franchise -- revealed to Tim that her parents provided the inspiration she needed to cheer herself on through the action movie's grueling schedule and physically demanding scenes.
"[My family] is what I would always think about when we were filming in some awful location, in some sweaty, dusty, chaotic mess," the beauty said. "I would be thinking, 'Just think of Mom and Dad and how happy they're going to be!'"
