In LaBeouf

Stunner from Down Under Isabel Lucas seems to be caught in a Hollywood love triangle as both Shia LaBeouf and Adrian Grenier are said to be vying for her affection.

Lucas was the "mystery passenger" when her "Transformers" co-star flipped his car in the early hours of Sunday morning. Despite a few minor abrasions, we're told Lucas went straight back to work and made a lucky escape.

But rumors have been bubbling over recent weeks that relations between Lucas and LaBeouf may be more than just professional, and this could be a possible reason for her split from Grenier just over two weeks ago.
