They’re just not keeping up any longer. Matriarch of the famous Kardashian family Kris Jenner, 58, filed for divorce due to irreconcilable differences in Los Angeles Superior Court on Monday.

Jenner and her husband Bruce Jenner, 64, have been married for 23 years but announced in October of 2013 that they had been amicably separated since June of that year. “We will always have much love and respect for each other,” they said in a statement at the time. “Even though we are separated, we will always remain best friends and, as always, our family will remain our No. 1 priority.” They continued to costar on E!’s Keeping Up With the Kardashians despite the separation.

According to TMZ, the couple has been working out a divorce settlement for the past few months. They had no prenup but have reportedly agreed to a property and asset switch with no spousal support to either side. They will share joint custody of their one minor child, 17-year-old Kylie. Bruce Jenner is allegedly planning to file a response to his estranged wife’s filing soon.

Neither Jenner has made a formal statement on the divorce at this time.
