Congratulations, Leo. Yesterday you became a year shy of over-the-hill (39!!). And, despite being a man of a certain age, you still manage to awaken the young girl inside of all of us. We could attribute our puppy love to your turn as Jack Dawson, or your first big role as a homeless boy who's given a fighting chance by Robin Thicke’s dad in Growing Pains, but when you uttered Shakespeare’s poetic words in Romeo + Juliet, you really won us over. A lot. The fish tank. The elevator kiss. Or, wait, the tryst in the pool! What you and Baz Luhrmann did with the 9th grade Lit staple was nothing short of miraculous (seriously, why did they ever bother to make a new one?). So in honor of the perpetual bachelor’s birthday (yesterday), enjoy this behind-the-scenes look at an iconic moment in Leo's past, and the moment that he officially become a heartthrob. Leo, you selfless, beautifully coiffed man. We’ll be envying Claire Danes and listening to Des’ree’s “Kissing You” on repeat all week. We’ll never you let go.
