Blake Lively's role as Carol Ferris in the new superhero flick Green Lantern (in theaters tomorrow) may be her biggest job to date. But, as of late, no one has been talking about that. Rather, what's getting even more buzz than her potential summer blockbuster film is her most recent role: Leonardo DiCaprio's new girlfriend. Although their relationship is unconfirmed, all of the recent paparazzi pictures are worth a thousand tabloid pages, a million pageviews, and 140 characters.

Since breaking up with his longtime girl, supermodel Bar Rafaeli, DiCaprio's been snapped everywhere from Cannes to Monte Carlo to New York City with the Green Lantern starlet. Clearly, there's no such thing as a mourning period for the A-list actor. But when you're the Leonardo DiCaprio, you have women willing to be on queue. The proof is in his dating history; just check out the guy's 10 Hottest Hook-Ups to see for yourselves.
