Is Robsten on the rocks?

Kristen Stewart's been one busy girl recently. Besides filming the last two Breaking Dawns, Kris also found time to make the flick On the Road with hot newcomer Garrett Hedlund. The two got super close on the set kind of like how Kristen and Rob did when they first starting filming Twilight together. Garrett even spilled that K-Stew would make him dinner and that they shared many on screen kisses. Naturally, rumors of a hook up started making the rounds on the web. But no worries, Robsten fans! Kris and Rob are still living the EdBella fantasy- she and Garrett are just buds. In fact, sources say that Garrett is secretly dating Gossip Girl's Leighton Meester!
