Do you know how long these parties last? How many people were there? How the room is set up? How long the journalists were there? Did the journalists ever go to the bathroom? Were they ever deep in conversation with anyone? How many times did they go the bar?
Each of these reports are somewhat similar, with different details because they're coming from three different people with different perspectives. They reported what they observed. But none of them could possibly have their attention on every interaction taking place during the party. And any introduction between AV & MF (and everything they've said indicates it was nothing more than a brief hello) probably took less than a minute. It's completely probable that that either wasn't witnessed or wasn't considered worthy of a mention in an article.
THIS. Incredible how some people are making such a big deal out of a simple statement. "We met on the dance floor". Meeting on the dance floor could last 1 minute, 3 minutes, 10 minutes, 30 seconds. Gosh. How are reporters supposed to report every single breath an actor takes? I can't believe we're really discussing this
