Will Jon and Kate Gosselin announce their divorce Monday?

Jon-kate Will Jon and Kate Gosselin announce their divorce on the Monday night show?

That's what everyone is wondering after the words "Jon and Kate Gosselin have an announcement" flashed on a TLC promo for the one-hour "Jon & Kate Plus Eight" special episode, airing Monday.

In the promo spot, Kate Gosselin says, "Recently, we've made some life-changing decisions -- decisions that will affect every member of our family, ones that we hope will bring each of us some peace."

Will they announce a divorce? Our inside sources say it's about 90% for the big D. Or at least the Big S (separation). But that's not official.

Is this all a big ruse? Will they keep playing out this marital discord number to stay on the covers of all the gossip weeklies and keep their ratings high?

Meanwhile, on the Jon Gosselin home front, the dude is reportedly shopping for an apartment in Trump Towers.
