Some helpful advice for "Twilight" stars Kristen Stewart and Robert Pattinson : Don't fuel rumors of a romance by getting all up in each other's business.

While on a junket with other"New Moon"cast members in Vancouver, Stewart and Pattinson took in a Kings of Leon concert, where RadarOnline seems to have caught the on-screen lovers canoodling.

Okay, to be fair, it's difficult to converse during a Kings of Leon concert, so it's entirely possible Kristen and Robert were swapping acting tips. But still, the shadowy shots are enough to set fans' tongues a-wagging, even if the tongues in film were firmly in their own mouths.

Rumors of a romance have followed Stewart and Pattinson since the first film, culminating in whispers that she was bearing his love child. Both actors have denied any sort of coupling.

Well, off-screen. You can see them grapple with human-vampire love again when "New Moon" comes to theaters Nov. 20.
