Oh, Thomas, Thomas, Thomas... The thing about TMZ, as trashy as they are (and they are among the trashiest of the trashy!) , the place is run by a former lawyer who evidently is a real hardliner about carefully wording anything they aren't sure is absolutely true to keep themselves from ending up in a lawsuit. They'll hang someone else out to dry in an instant, but they don't directly quote people unless they feel it's airtight. So if they're plainly saying they talked to Tom Sr. and he said these things, then very likely that's what happened.
Which is beyond idiotic on his part.
I think it's very important that he said he's dropping out of the wedding. He's probably been getting an earful from Meghan and/or KP about the photo stunt, but surely KP wanted to just tamp it down, keep plans the same for the wedding, and then work on getting him better under control in the future. I wouldn't be surprised if a sort of intervention involving a short yet intense "how to ignore the paps" training session was being planned for him while he was in town, given how boneheaded his last move had been. Shoot, maybe he can sense that's coming and he's taking the coward's way out to avoid it.
I just wonder if he'd fully sorted out with Meghan and KP that he wasn't coming or if this is a spur of the moment decision they were trying to talk him out of...and then he decided to blab about it in the heat of emotion.
