Zac Efron is now a single man, so why NOT cozy up to his smokin' hot co-star, Emily Ratajkowski?

On Wednesday the news broke that Zac and much older lady love Michelle Rodriguez had split, and that same afternoon we snapped the 26-year-old actor on the set of We Are Your Friends in Los Angeles, and after working up a sweat on a run, he got super close to Ms. Ratajkowski. The previous day we spotted him flexing his muscles and giving a male pal a back massage, so who knows what he'll be up to today!

The film is about a young DJ named Cole who ends up falling for the girlfriend of his mentor, and between the love triangle, Zac's ridiculously fit body and a soundtrack that's aimed to appeal to a younger demographic, it sounds like this movie could be pretty interesting. Or pretty bad. But still, pretty interesting, right?
