Rob Pattinson and Kristen Stewart Asked About Off-Screen Chemistry

On Thursday during a Comic-con question-answer with the press, a reporter named Bob Stencil was ballsy enough to ignore the request that no press ask about any extra-curricular relationship between Rob Pattinson and Kristen Stewart.

The two had no comment. What do you think, are they sick of answering the question or is something really going on between them?
