J.LO NO-GO: Jennifer Lopez, 34, and Ben Affleck, 31, have announced that they are postponing their wedding, initially set for Sunday in Santa Barbara, Calif. The power couple said the press leaks and resulting media frenzy were turning the event into a “circus” and detracting from the spirit of it. There was speculation that the wedding was actually still set to go on as planned, or that Affleck got cold feet, but the pair made a public showing at the Ivy restaurant in Beverly Hills Thursday night to fend off rumors of any trouble.

RYDER’S CAUSE: Winona Ryder sponsored a Los Angeles art show to raise awareness and show support for the “West Memphis Three” — Damien Echols, Jason Baldwin and Jessie Misskelley — inmates she believes were falsely accused and imprisoned for the 1993 ritualistic murders of three 8-year-old boys in West Memphis. Acknowledging her own brush with the law (Ryder was convicted on grand theft charges following a Beverly Hills Saks Fifth Avenue shoplifting trip in December 2001), the “Girl, Interrupted” actress, 31, told USA Today: “I’m sure there’s going to be a lot of jokes.”

HOMEWARD BOUND: Simon & Garfunkel will hit the road for “Old Friends — The 2003 Concert Tour,” the first S&G concert tour in 20 years, kicking off Oct. 18 in Auburn Hills, Mich., and traveling to U.S. arenas through mid-December. Encouraged by their reunion performance at this year’s Grammys, the off-again, on-again friends will travel to 30 cities in all — with date and location specifics to be made available in local newspapers. Tickets go on sale Monday.

SKAKEL ANEW: Hope Seeley, the attorney for Kennedy cousin Michael Skakel, intends to file a request for a new trial in the 1975 murder of her client’s then-neighbor, Martha Moxley, based on what Seeley calls new evidence, CNN reported. The petition is expected before the end of this month. The Skakel case surfaced again after the Hartford (Conn.) Courant newspaper reported that a former classmate of Skakel’s, Gitano "Tony" Bryant (who is a cousin of Los Angeles Laker Kobe Bryant), told defense attorneys in a videotaped statement that two of his friends had admitted killing Moxley.

KIM’S CALL: “Sex and the City” vixen Kim Cattrall, 47, will produce two specials for HBO, and she says the programs will reflect her taste, reports the New York Post. Her programs — for her company, Fertile Ground Productions — will be a new version of Clifford Odets’s play about a washed-up actor and his wife, “The Country Girl” (in which Cattrall will assume the role that won Grace Kelly an Oscar when she starred in the 1954 movie version) and an educational documentary titled “Sexual Intelligence.”
