Spotted, Robert Pattinson and Kristen Stewart holding hands as they left Paris today! Amidst all the speculation of are-they or aren't they this certainly seems to seal the deal — the two look oh so happy. We saw Rob's big smile as he left his hotel after their adorable press conference with Taylor this morning. Amid all the magazine mania especially the romantic Harper's shoot, this is the best. A short while later, they landed in London for the next leg of their promotional tour. We've posted hundreds of photos of the New Moon stars all over the world, but this might just be the sweetest set of all — so what do you think — do you think this is proof that Robert and Kristen are more than friends?
