Notice how the photo is cropped so you don't see the ice, he was taken off guard and they steadied him. For over two years the slime gossip paps have been trying to get their money shot of this nice guy. The shippers and people who make their money selling lies even resorted to fake and photo shopped pics like the ones leaving Paris and the non-kissing ones of them at a loud concert.
No matter what the fans want, these two will never be more than friends. The reasons will be evident soon enough. Just be glad that he is a loyal and kind guy and let him have a life.
I believe that these photos are from the premier that had ice on the ground. Rob almost took a header on the slippery ice. Rob's manager and agent would not let him go out the front stumbling. He likes his beer but he is not a fool nor in two years has he ever been a mess in public. This is about paps and other studios trying to ruin his reputation.
There were tons of fans there and they were trying to get him to not get bogged down.. Kristen was only at the NY one and had gold pants on. Her movies are Summit too so they were trying to get them free publicly. They are appearing in public together as they are friends. Summit wants to stir the speculation that they are together so it keeps interest in Eclipse and Breaking Dawn. By all accounts and going by what Kristen indicated at Sundance Film Festival, they are merely good buddies.
