Rob Pattinson and Kristen Stewart have been keeping their love affair on the down low ever since it started (might have had something to do with the fact that Kristen still had a boyfriend!) but now, they're taking it a step further, calling the reports they're hooking up totally "false!"

The New Mooners recently spoke to Vanity Fair:

    For the record, however, Pattinson says the rumors of a love affair are false: “It doesn’t make any difference what you say [to the tabloids]. I’ve literally been across the country [from Kristen], and it’s like ‘Oh, they were on secret dates!’ It’s like ‘Where? I can’t get out of my hotel room!’ ” Stewart is even more emphatic: “It’s so retarded,” she says. “We’re characters in this comic book.”

Rob and Kristen have been careful to keep their relationship under wraps, trying not to be photographed together. Last week the couple arrived in LA together from the New Moon set, where a spy told X17online they looked mighty "cozy" on the flight, but separated the minute they landed.

And in an online poll, most of you told us you believe the on-screen couple is still "friends and lovers" off-screen, as well.

So why are they going above and beyond to deny something we all know is true?
