Is this picture real ou was it photoshoped? Does this pic proves that Robsten actually had sex?

I give toi 100% that it's photoshop, because I use photoshop for last 8 years )) his neck has different color than face and it's too big, he's got long and thin neck in reality, and look on the sholder, near Kristen it's really too big almost like his face ))

Its photoshopped
