Like the prince desperately searching to find the maiden who fits the glass slipper, people have been scouring Los Angeles to figure out who the female passenger in Shia the Beef's Flaming Beertastic F-150 of Death was. Nothing was known of the lady other than the fact that she yelled "FUCK!" after the truck went tumbling, but today, she has been identified! Her name is Isabel Lucas, she's Beef's Transformers 2 costar, and she's Adrian Grenier's girlfriend. Whoops. New York Daily News reports:

Shia LaBeouf may have more to worry about than the drunken- driving charge he got after crashing his truck with Australian hottie Isabel Lucas strapped in the passenger seat.

Lucas, one of LaBeouf's comely co-stars in the upcoming "Transformers" sequel, has been dating actor Adrian Grenier for months.

[Grenier] was testy and had no comment Monday when asked how Lucas was feeling after the smashup with her other leading man.

Lucas, 23, was in LaBeouf’s car when it collided with another vehicle at a West Hollywood intersection early Sunday morning and rolled. She was treated for minor bumps and bruises at Cedars-Sinai Medical Center and released.

“She was in the car….They’re friends,” a movie source said of the LaBeouf-Lucas connection. The source said the two have been working a lot of late nights on the set and most likely were together to let off some professional steam.

Generally, when a man finds out that his special lady has been stepping out with a drunk dude, he'd issue a hearty beatdown punctuated by a few kicks to the groin, so under normal circumstances, we'd tell Shia to go secret himself away in a bunker or something. But it's Adrian Grenier. What's he gonna do? Break out the pomade and style Shia to death?
