If their quality time spent overseas didn’t get your wheels turning (or at least make you green with envy), this paparazzi pic courtesy of Us Weekly (via OMG) makes it pretty much official: Blake Lively (Serena) and Leonardo DiCaprio are definitely an item — or something more than just friends.

Despite attempts not to be photographed together, the Gossip Girl star and her big-name beau — who will soon start filming The Great Gatsby — were spotted holding hands during a moonlight stroll on the French Riviera. "Her face lit up when Leo was talking," a spy told Us Weekly.

"He had introduced Blake as his girlfriend," added another source. "I would say they're totally smitten!"

We’re totally smitten just from the idea of this mega-hottie-mashup — which we can only assume stared months ago during what was deemed a “business” dinner. But what do YOU think? Do Blake and Leo seem like a Hollywood ‘ship made in heaven? And is anyone totes hurting for Penn Badgley (Dan) right now? It’s Leo-friggin-DiCaprio. Yeah: Ouch!
