Kissing Co-Stars: Robert Pattinson and Kristen Stewart? Perhaps

In between filming "Eclipse," the latest "Twilight" movie, Robert Pattinson, 23, and Kristen Stewart, 19, took some time to take in a Kings of Leon concert . . . and perhaps each other.

Newly arrived in Vancouver, the cast decided to take a break from filming and spend time together. But Pattinson and Stewart seemed more interested in each other than bonding with the rest of the cast.

New photos on Radar Online show the co-stars getting quite cozy in the audience. Could their on-screen romance be translating off-screen? The two did look quite close at the recent Comic-Con.

Of course, as E! Online speculates, "The two colleagues might just be discussing character motivation or whatever over the din of the band at a loud concert."

But, as the Los Angeles Times reports, "The buzz is that their interaction heated up when KoL played 'Sex on Fire.'"

It's up to you to decide.
