Al Pacino -- Hooo Ahhh!! GF Is Sheer Hotness

Congratulations to Al Pacino's smoke show of a girlfriend -- she actually found a way to upstage the acting legend ... simply show off your ridiculous body in a see through top!

Pacino and Lucila Sola strolled through JFK airport Wednesday. The 35-year-old Argentinian actress has been dating 74-year-old Pacino for a couple years now.

Lucila made it blatantly obvious why Al was sporting a sly smile.

And ya just know the answer to the question we're all thinking is ... yes, she does.
