From last night's episode thread:
TMZ has Ballas denying it happened.
I've no confirmation of anything, but I can't help but think there's something to it. Even if blown up by the tabloids, US (to my knowledge) isn't the Batboy school of reporting and they must have some basis.
I think Us Weekly has gotten rather bad over the past couple years. Not Batboy kind of stuff, but, once they commit to an angle on a celeb/story, they stick with it well past reason. (And they will keep dragging it out whenever they get even a teeny hint of a reason to do so). I could easily see a scenario where, after the initial story from his ex last week, they may have some "in" with the ex, so when given an opportunity to take a story and twist and magnify it to make him look like some rageaholic douchebag with a trigger temper, they jumped on it, because it just fills in the gaps in the ex's narrative for them quite nicely.
I'm not saying nothing happened at all, because it seems obvious, to me, that there is some tension and there likely was some form of disagreement between the two, but I'm also going to take Mark at his word when he says the whole "melt down" and him having to go storming in to protect Kym is BS. I think I would be shocked to find that any pair has gotten through a season of this show without arguing. They spend too much time together, learning something brand new is stressful, and the competitive urge kicking in just adds to that mix.
Having said all of that, if Jaleel gets the boot tonight, I might be willing to believe it's possible the Us version wasn't as wildly exaggerated as I currently think it is. I say that because if this blow up did happen at all resembling what was reported, and you combine it with allegations from his ex of abuse, and you don't do something about it, you're opening yourselves up to some seriously ugly future incidents and potential liability. I could see a situation where, if they believe he needs some help, they approached it as "OK, if you agree to get help, we let you dance Monday, you get eliminated, and then you get yourself into counseling, and we will keep this as quiet as possible or downplay it as much as possible if it gets out." Mark's denial today then turns to him going company man on the paparazzi.
If he sticks around beyong tonight, though, I'm going to believe that while they did have an argument, and there is some tension, it's been wildly exaggerated by Us Weekly to fit some narrative.
