Will Jon and Kate Gosselin Separate?

June 22, 2009 — -- After months of unfavorable tabloid coverage and speculation about the state of their marriage, Jon and Kate Gosselin are set to make an announcement tonight on their popular reality series, "Jon and Kate Plus 8," about their family's future.

"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," Kate Gosselin said in the episode airing tonight. A promotion for the hour-long special episode, which airs on TLC, has captions like "a family in turmoil," "a relationship at a crossroads," and "Where do they go from here?" while showing images of a once happy Gosselin clan.

"If you're a betting, man, you're betting there is either going to be a divorce or at least a separation," said Entertainment Weekly television critic Ken Tucker.

The statement comes just 10 days after the couple's 10-year wedding anniversary. The Gosselins, who are parents to a set of twins and sextuplets, have become the country's most discussed couple after allegations of extramarital affairs arose.

"Doesn't matter where Jon and I are in our relationship. My kids still matter the most to me. We haven't really known where we were going, but we've been dealing with this for a long time. A slow progression that has not popped up one day, it's not been like a secret," Kate Gosselin said.
