It's final, Jon and Kate Gosselin did an announcement of their split and filing for a divorce in their June 22nd episode TLC reality show. No specific caused was being afforded but with the exception from Jon who felt no desire in putting any effort to make the marriage work but both expressed that constant personality clashes were creating no benefits for the kids.
Their public statement regarding their legal separation were combined by installing the new playhouses for the eight children. You can pop over to the TLC website to see more photos of the playhouses.
Or you can check the Crooked House website to get more information about the kids playhouses. I heard these playhouses are being sold too from Amazon.com with the price of US$ $2,492.27 for one standard playhouse like the lavender color shown below.
