Don't paparazzi mainly ask them questions when there is a rumour going around? Because, if that's the case, they'd probably be screaming at Kristen (mainly): "KRISTEN! KRISTEN! IS IT TRUE THAT YOU'RE CHEATING ON ROB WITH YOUR SWATH DIRECTOR?" I think that if that ACTUALLY happened, Rob would definitely be interested in that fact and we'd have pictures where Rob is looking shocked and confused. Maybe even angry and walking away from Kristen. My belief is that it is ALL a rumour. Because, if it wasn't, don't you think that the pictures would have come out on the SAME DAY? If I was an HONEST paparazzi and my job was to tell the TRUTH and I found out that a celebrity who was in a relationship was cheating on their partner with another person, I would snap the photos and send them IMMEDIATELY to get them published ON THAT SAME DAY! Wouldn't you?
