Summer's heating up for Dianna Agron and Sebastian Stan! The new couple were first spotted making out in late May, but they were forced to take things slow while Dianna criss-crossed the country during the Glee Live! tour. Now that it's done, however, it's full-speed ahead! "Dianna is flying out to LA to be by Sebastian's side while he promotes Captain America," reveals an insider who chatted with the Gossip Girl star at the recent Carrera Sunglasses Escape in NYC. If things go well, they're even considering moving in together!

Though it seems like they might be moving fast, Dianna definitely has a history of jumping head-first into new relationships. She and ex- boyfriend Alex Pettyfer moved in together just months after they started dating in 2010 and were even rumored to be engaged less than a year later! Of course, that all ended almost as suddenly this spring. And since Alex was reportedly very aggressive to Dianna in the wake of the breakup, she definitely deserves to rebound with a good man.
