UPDATE: Kato Kaelin told TMZ that he never told New York Post reporter Cindy Adams that O.J. Simpson definitely killed his wife. Kato said he has expressed his opinion before, and that he thinks Simpson did it, but that "I have no first hand knowledge."

Earlier:

Now he tells us.

The freeloading houseguest who became a minor celebrity for his meandering testimony at the O.J. Simpson murder trial now feels safe saying he thinks Simpson killed his ex-wife and her friend.

"The statute of limitations has now passed . . . so I can now say . . . yes, he did it," golden-haired Kato Kaelin admits to gossip columnist Cindy Adams.

It's been more than 18 years since Nicole Brown Simpson and Ronald Goldman's murdered bodies were found in Los Angeles.

Prosecutors called on Kaelin, now 53, during the trial as a witness who could detail Simpson's movements on the night of the June 1994 killings. But during four days on the stand, the struggling actor provided an inconsistent version of events. Prosecutor Marcia Clark would ask that he be declared a hostile witness, because he wasn't forthcoming under questioning.

Asked by Adams why he didn't tell the truth, he says: "I was too scared. I was terrified."

Now hosting a sports show called "Tailgating with Kato," that features Borscht Belt-style comedy, Kaelin has made a round of media appearances recently. He told Headline News last week that he doesn't think the former football star is innocent.

"So, do I feel he's guilty? Yes, but can I prove it? No," Kaelin said. "And that’s what happened in the court of law."

Kaelin's comments come amid sniping between Simpson's former attorneys and the prosecution. The burst of interest in the case was ignited by O.J. prosecutor Christopher Darden's comments this month alleging that Simpson's attorneys tampered with the infamous pair of gloves.

Simpson was found not guilty in the murder trial, but was later found liable in a civil suit filed by the victims' families. He's currently incarcerated for an armed robbery and kidnapping in Las Vegas.
