The divorce papers add that the exes will seek joint custody of Kylie, the only minor child.

The couple, who first got together in 1991, first announced their separation Oct. 8, 2013, but the papers cite that they separated earlier in June.

"We are living separately and we are much happier this way," the couple told E! News in a statement last year. "But we will always have much love and respect for each other. Even though we are separated, we will always remain best friends, and as always, our family will remain our No. 1 priority."

Even in divorce, the two remain friends, with Kris calling Bruce "one of the most amazing men I know" in a tweet back in April at the time of their anniversary.
