It's Over: Kris Jenner Files for Divorce from Bruce Jenner

The Kardashian matriarch, 58, filed for divorce Monday, 11 months after the longtime couple announced their separation, PEOPLE confirms.
Kris wed the former Olympian, 64, in 1991 and together they are parents to daughters Kendall, 18, and Kylie, 17.
"They both did it together," a source close to the family said of the divorce filing. "It's all done and [there's] no drama or messiness. They worked out all details over the last few months."
According to court documents obtained by PEOPLE, Kris has requested joint physical and legal custody of Kylie (their only minor child), and that she keep all her jewelry and assets amassed since their separation. She requested all other assets be divided later.
The duo announced their split last October, though court papers reveal they actually separated in June 2013.
"We will always be the best of friends, because that's the dynamic of our relationship," Kris told PEOPLE shortly after they announced their separation. "We definitely get along as a family and with the kids; we're so connected in that way. We love each other."
As to what led to the split, Kris herself has said she isn't certain.
"I don't think it was the pace of life. We've always gone 150 miles per hour, and Bruce has more energy than anybody," she said. "I just think it has evolved. I really can't put my finger on it. We're just happier now."
The couple previously addressed their split on their reality show, Keeping Up with the Kardashians.
