Keeping Up With The Kardashians matriarch Kris Jenner is ending her 22-year year marriage to her Olympic decathlete husband.

She has filed to divorce Bruce Jenner, citing irreconcilable differences.

The pair's relationship and its troubles have been featured prominently on the reality show that focuses heavily on Kris' daughters from a previous marriage, Kourtney, Kim and Khloe Kardashian.

The women and their brother Rob were born during Kris' previous marriage to Los Angeles lawyer Robert Kardashian, whom she divorced in 1991.

Kris and Bruce have two children together, daughters Kendall and Kylie. The divorce petition seeks joint custody of 17-year-old Kylie.

Bruce won the gold medal for the men's decathlon in the 1976 Montreal Olympics.

Court filings say he and Kris separated on June 1. They do not provide any additional details or how the pair will split their assets.

The divorce was first reported by celebrity website RadarOnline.com.
