O.J. Simpson trial witness Kato Kaelin and his wife Nan Xue Kaelin filed a joint petition for divorce in Los Angeles County after less than five years married.
Kato Kaelin is getting divorced. The longtime O.J. Simpson trial witness and his wife, Nan Xue Kaelin, filed a joint dissolution petition Wednesday in Los Angeles County Superior Court, ending a marriage that ran less than five years.
TMZ broke the paperwork. The filing details obtained by TMZ on the joint petition and the couple’s August 2025 separation date show the pair married on September 17, 2021, and separated on August 1, 2025, with no minor children, no community real estate, and no shared liabilities to divide.
Both parties waived spousal support. The petition’s joint status and the lack of contested property suggest a low-drama split.
Kaelin kept the statement gracious. “Nan is the most wonderful and beautiful woman in the world,” he told the outlet. “We will 4EVER be great friends and have laughter between us. Please respect our privacy.”
Kaelin, 67, has been a pop-culture fixture since 1995. Wikipedia’s profile of Kaelin’s role as the Rockingham guesthouse tenant and prosecution witness in the O.J. Simpson murder trial notes that one survey during the trial found 74 percent of Americans could identify him by face.
The trial cemented his celebrity. He was staying in Simpson’s Rockingham Avenue guesthouse on the night of June 12, 1994, when Nicole Brown Simpson and Ronald Goldman were killed, and his testimony helped prosecutors establish a timeline for the evening.
His view of the case has shifted publicly over the years. ABC News’s 2016 Barbara Walters sit-down in which Kaelin said he now believed Simpson was guilty marked his most candid public reassessment of the case, more than two decades after the not-guilty verdict.
The Wednesday filing closes the chapter cleanly. Nan Xue Kaelin has kept a much lower profile than her about-to-be ex-husband, with no public statement attached to the petition.
For Kato, the math is roughly four years and eight months of marriage, ten months separated, and a single joint petition with no contested property. As Hollywood divorces go, it is the least Hollywood version of one.
