Leonardo DiCaprio And Blake Lively: King And Queen Of The World?

Lake? Bleo? Please excuse the lame attempts at guessing a mash-up name, but if the rumored romance between Blake Lively and Leonardo DiCaprio is legit, it might almost be worth resuscitating this old trend. Almost. The buzz of a possible relationship has been building for a while now, but there's nothing like a seemingly romantic weekend to push you to the top of the gossip heap.

The twosome was seen strolling together in moonlit Monte Carlo over Memorial Day weekend, reports Us Weekly. The mag quotes witnesses who say Leo seems totally smitten and even introduced Blake as his —wait for it—girlfriend. That's right, folks: The G-Word. It must be love.

The Us Weekly report is basically overflowing with sweet nothings Leo and Blake are allegedly saying (and thinking and feeling) about each other (all from unnamed witnesses of their Monte Carlo lovefest). A sampling:

"He looked very in love."

"Her face lit up when Leo was talking."

"I would say they're totally smitten!"

Let's all say it together now: Awwww!

Leo has a history of falling for models (in fact, he and model Bar Rafaeli called it quits just a few weeks ago), so a lesser girl than Blake might be a little intimidated, but with her poise and attitude, we're sure insecurity will be a non-issue for our favorite gossip girl. Our oh-so-stellar Photoshop skills aside, it looks like Leo might have found his queen of the world.

Do you think Blake and Leo make a cute couple? Or are you still reeling from her split with Penn? Tell us in the comments and on Twitter!
