What to Know About Kato Kaelin
Early Life and Family Background
Kato Kaelin was born on March 9, 1959 in Milwaukee, Wisconsin. As a child, he got his nickname from the character Kato in the TV show The Green Hornet. That role was played by Bruce Lee. The name stuck, and the world now knows him by it.
He later moved to Hollywood to chase acting. In December 1992, he met Nicole Brown Simpson on a ski trip in Aspen, Colorado. They became friends. He later moved into the guest house on her property on Gretna Green Way and stayed about a year. He paid rent and helped care for her two children, Sydney and Justin.
When Nicole moved to a home with no guest house, Kaelin chose not to live inside it. He moved into the guest house on O.J. Simpson’s Rockingham Avenue property instead. On June 12, 1994, he ate McDonald’s takeout with Simpson. That same night, Nicole and Ronald Goldman were killed.
Career
Kaelin’s early screen work was small. He was in the beach comedy Beach Fever in 1987 and the horror movie Night Shadow in 1989. Then came the trial.
At the 1995 trial, he was a witness for the prosecution. He said he could not account for where Simpson was between 9:36 p.m. and 11:00 p.m. on the night of the killings. Prosecutor Marcia Clark had him declared a hostile witness, which let her question him more sharply. Kaelin has said he thinks Simpson did it, but that he has no firsthand knowledge.
Soon after the trial, he showed up on the first episode of MADtv in October 1995 and on Mr. Show with Bob and David in November 1995. In 1995, he also hosted an afternoon talk show on the Los Angeles radio station KLSX, which lasted about a year. In 2002, he joined Celebrity Boot Camp and The Weakest Link. From June 2005 to 2006, he co-hosted the court show Eye for an Eye. Since 2011, he has hosted Tailgating with Kato.
In 2019, he joined the second American season of Celebrity Big Brother. He was voted out on February 4, 2019, finishing in 8th place out of 12 houseguests.
After the trial, the tabloid National Examiner ran a cover that said “Cops think Kato did it!” Kaelin sued for libel. A lower court threw out the case, but the Ninth Circuit appeals court brought it back. The ruling became a landmark in libel law because it said a headline can be libel. He later settled his 15 million dollar lawsuit out of court for an amount that was never shared.
Age
Kato Kaelin was born on March 9, 1959. On October 19, 2026, he is 67 years old. He will turn 68 on March 9, 2027.
Religion
We could not find a reliable public statement from Kato Kaelin about his religion. Some sites list one without a source, so we will not guess.
Wife and Marriage History
Kaelin has been married twice. His first wife was Cynthia Coulter. They married in 1983 and divorced in 1989. His second marriage was to Nan Xue Kaelin on September 17, 2021. The two separated on August 1, 2025 and filed to end the marriage in May 2026.
He is also reported to have a daughter, Tiffany Kaelin Knight.
Net Worth
Nobody has shared a verified money report for Kato Kaelin. Most celebrity sites guess his net worth at about 2 million dollars, which they link to years of TV, radio, film and reality show work. Other sites say 500 thousand dollars, and a few say 3 million. Treat all of these as rough guesses, not facts.
Parents
Kaelin was born to Al Kaelin and his wife. His mother’s first name is written as Izzy on some pages and Lizzy on others, so we are not sure which spelling is right. Little else about them is public.
Height
There is no reliable, official height for Kato Kaelin. Websites list very different numbers, from about 1.77 meters to 6 feet 3 inches. Because the numbers do not match, we will not print one.
