Isabel Lucas polka dots dress leggings head band guitar luggage lax airport

Aussie hottie Isabel Lucas was looking blonde and beautiful at LAX yesterday where we caught her arriving, with her carry-ons in hand. Included a ... guitar? Who knew the Transformers: Revenge of the Fallen could strum a tune?

I guess Jake Gyllenhaal may know something about that. Rumor has it, he's moved on from Reese with the 25 year-old, though Lucas has said about her relationship with Jake that it's "purely platonic." But do we believe it?
