DIED: "Eight Is Enough" star Lani O'Grady, 46, was found dead in her mobile home in Santa Clarita, Calif., on Tuesday. The actress, who played Dick Van Patten's sensible oldest daughter Mary on the ABC hit show from 1977-1981, had drifted away from acting after her stint on the show. The cause of death is under investigation, though no foul play seems apparent. O'Grady was the sister of Don Grady, who played Robbie Douglas on the 1960-1972 comedy "My Three Sons" . . . AUTHORED: Chelsea Clinton will write a story for Talk Magazine about her experiences and feelings about the World Trade Center attack. The former first daughter had planned to go jogging around the towers the morning of the tragedy . . . HELPED: Liza Minnelli will lend her voice to "HeartSong: The Heroes' Concert," a Broadway and cabaret benefit for the Twin Towers Fund on Oct. 8, at New York City's Bottom Line . . . TROUBLED: Former boxing heavyweight champion Mike Tyson is being investigated by police for the second time in two months on a sexual assault allegation. Police searched Tyson's Las Vegas home on Wednesday for evidence related to a recent assault. No charges have been filed . . . SKIPPED: The words "Live from New York . . . It's Saturday Night Live!" will be uttered this week by Reese Witherspoon, who'll host the season's premiere on Saturday. But Ben Stiller, the star and director of the comedy Zoolander, recently turned down next week's hosting gig in light of the Sept. 11 tragedy. "It was a really hard decision for me," he told the New York Times. "I didn't know how to be funny right now in the way it takes to do that show -- the amount of energy it takes."
