Pictures or it didn't happen? As much as I know everyone will take the pic and re-post it, I'll respect Moon's "please don't take the picture" and send you to Letters to Rob for the pic :))
UPDATE: Posting with permission from UnintendedChoice, please don't repost ;)
She did see them, I trust Moon's eye sight. You can tell from both of their postures anyways ;)
What does this mean? It means they went to a concert together :) I can't/won't speculate further but please go nuts in the comments section...
P.S.: I'm sorry Rob/Kristen I know you didn't want to be seen and I do fell crappy for posting this but it's out and at least I report it without speculating...
