I hope it's not true. I'm whatever about them getting back together (if the rumors are true) but it would just be controversy bait to have him in the video with her.
If even true, why would they just put it out there he's in the video? Obviously if it's supposed to be some kind of "shock," they wouldn't include him in these, as stated, professional photos.
But like I said, you've learned before and if he pops up in the video you'll learn thrice more.
