Rumours that Vince was pissed that he said he met Vince backstage, since in kayfabe Vince isn't at the shows. Which is why he seemed very quiet and subdued after that. Vince must have shouted at him in the headset.
Which makes it even more hilarious, since Vince must have already been pissed before Lavar and the fam did their thing.
I'm sure every commentator has Vince in their ear at some point or another so most likely. It's even happened to WWE commentators, they get the personality sapped out of them sometimes when they're live on air.
It seemed like he was completely disinterested in the product and was only there to plug Transformers. Cole set him up to reveal that Sheamus was in his next movie and he started talking about one of his Transformers co-stars instead.
They must have said something because when they came back from the break he immediately complimented Sheamus and Cesaro. He was another completely useless celebrity guest. He didn't want to be there and it showed.
Most celebrities don't want to be near a wrestling show.
Even the ones who were or are still fan of the business don't want to be associated with wrestling, and its not about WWE is about all wrestling, its 2017 and is still view as a low class form of entertainment.
Wrestling is like porn, you can watch it all you want but you don't want anyone around you to know it, know about wrestlers names and moves its like knowing porn actresses names and movies, it makes you look ... pathetic.
