If Robert Pattinson and Kristen Stewart aren't dating, you could have fooled us.

They looked extremely hot together at the recent Comic-Con, above, and it sure looks like something was going on at the Kings of Leon concert Saturday night.

New photos of the lovers (or just really, really close pals) have surfaced on RadarOnline from the concert in Vancouver, Canada.

The whole "Eclipse" cast was there, but Robert and Kristen are seen EXTREMELY CLOSE to each other. We're talking kissing close in these photos

According to observers, Robert, 23, and Kristen, 19, were having a great time together, smoking and drinking at the concert.

And the buzz is that their interaction heated up when when KoL played “Sex on Fire.”
