I'm sorry if the image is very hard to see, no HQ pictures yet. But a very cute Robsten moment and not the only one. Below is the Madrid fan event, i am sorry that it is just a link but WELL worth the watch:
The person who shot the video didn't get the Robsten comment, but Rob was simply asked what the advantages would be if he was a vampire, this is Rob's answer:
"You get to date a girl like Kristen Stewart" The fact he didn't say Bella, the fact Kristen was totally embarressed and Rob was stuttering for a back up plan, the crowd was chanting for them to kiss but Rob came to the rescue and said "and get to beat guys up like Taylor Lautner."
All i can say is that they were very touchy feely.
