Messages have been mixed since then. In April and May, ahead of the show's June return following a hiatus, Kris was seen wearing her wedding ring...
... and posted on Instagram celebrating the couple's 23rd wedding anniversary.
They were even seen holding hands ... spotted by paparazzi at the airport, where the Kardashians are frequently photographed.
And E!, the show's home network, teased the season as a way to watch their relationship evolve.
On the show we saw the two live apart, but spend time together, never nailing down exactly what was going on.
So, it seems like their divorce filing, just after the season finale, again raises a question we asked nearly a year ago: Were their relationship troubles just used as a plot line for the pair's "reality" show? A way to drum up publicity as the ratings faltered?
In fact, the announcement comes just a day after the show's finale in the U.K.
Yet according to various reports on the news, sources say the two had been working out the terms for months.
Ultimately, the divorce is said to be amicable. There is no word on how all this will factor into a plot line for season 10.
