As far as hints go, Kim Cattrall's was about as subtle as her form-fitting Valentino gown. Upon hearing her name called as the winner of a Golden Globe award at L.A.'s Beverly Hilton on Jan. 19, the Sex and the City vixen, 46, hugged many a well-wisher—but barely acknowledged the man at her side: her husband of four years, audio equipment exec Mark Levinson. So much for the guy who, she told PEOPLE in 2001, "taught me about patience and understanding"—not to mention the way to sexual fulfillment as documented in the how-to book the couple wrote last year, Satisfaction: The Art of the Female Orgasm. In a display of foreshadowing onstage, Cattrall acknowledged her unwavering kinship with her female costars and noted, "Men may come and go."

As of now, Levinson, 56, is officially gone. While the thrice-married Cattrall was at the Comedy Arts Festival in Aspen on Feb. 27, her rep confirmed that the two are "taking a break." Why? "No exact reason," says a friend. "No one is dating anyone else. It just happens." In Aspen, Cattrall wouldn't comment on the split, though she seemed happily low-key, making hot-cocoa runs and snowshoeing with buddies. "We went up the mountain," she said, "saw this incredible view and came back down." Next view: learning how to be a single woman, in real life, while taping the final season of Sex. Says one pal: "She's going to hang with her friends."
