And content on the home front -- despite her split earlier this year from Whitcomb, 32, her beau since 1999. In quiet Hailey, Moore's life revolves around daughters Rumer, 14, Scout, 11, and Tallulah, 8, and the standard parental procession of soccer games, recitals and school fund-raisers. Already known for having forged one of showbiz's more amicable divorces, she and Willis, whose marriage crumbled in 1998, have drawn even closer in recent months. A year ago Willis, 47, spent more than $7 million for a 7,300-sq.-ft., five-bedroom house directly across the street from Moore's $2.8 million, six-bedroom spread. (Willis's former home base, a $2 million estate where he lived with Spanish model Maria Bravo until their split in 2000, was 10 miles from Moore's.) In July the ex-spouses visited Disney World together -- staying in separate suites at the Animal Kingdom Lodge -- to celebrate Scout's 11th birthday. "It's a huge priority for both of them that the kids get to see as much of them as they can," says Campbell, whose three children's activities often intersect with the Willis youngsters'.

Around Hailey the exes' togetherness has sparked speculation of a romantic rapprochement. A possibility? "All I can tell you is that she's very happy and content," says Todd. "Liz Taylor, Richard Burton? My own personal wishful thinking. But you never know. It could happen. Demi and Bruce are good together even as friends and parents, but yeah, you know, they're good together."

For three years Moore and Whitcomb also seemed to mesh despite their differences. The laid-back Aspen, Colo., native -- described by one acquaintance as "the most unflashy guy who ever walked the planet" -- initiated the split in June. "The relationship just wasn't working for him," says a friend of Whitcomb's, who adds that the "final straw" was Moore's taking the role in Angels. "He is not into all that Hollywood stuff." Whitcomb remains friendly with Moore and her children, with whom he had grown close, says his friend. "They still talk."

As Moore reenters the showbiz orbit, Willis hasn't been the only flashy guy in her life. She attracted attention in July by watching a Red Hot Chili Peppers concert from the front row, then turning up at a party days later with the band's frontman, Anthony Kiedis, who turns 40 Nov. 1. "They're friends, she's a fan, it's nothing more than that," Kiedis's spokeswoman said at the time. Early in October Moore sparked more buzz by taking in a screening of Swept Away with Guy Oseary, Madonna's Maverick Entertainment business partner. But at Oseary's 30th-birthday bash in Beverly Hills on Oct. 19, another woman was on his arm -- and Moore, who came with a girlfriend, danced with him only briefly. "He's not dating Demi, they're just really good friends," a pal says of Oseary, who has previously stepped out with Gwyneth Paltrow and model Eva Herzigova. "They talk on the phone and go out to dinner." (Gossips, restart your engines: At the party Moore did vamp to Madonna's "Vogue" with actor Owen Wilson.)
