Don't look for Demi Moore in Hollywood these days, PEOPLE reports in its latest cover story. She's too busy enjoying her life in Hailey, Idaho, as a devoted mother to her and ex-husband Bruce Willis's three daughters -- Rumer, 12, Scout, 9, and Tallulah, 7. Then there's her stable two-year romance with Oliver Whitcomb, 30, an Aspen native who lives in a rented apartment in Hailey. "She's a classy lady, and he's a grounded guy," says a pal. Moore, 38, frequents not one but two local coffee shops to down 20-oz. double-skinny lattes with nonfat milk. In between, she carts her kids from school to horseback riding lessons, gymnastics classes and soccer practice. And she even gets to dabble in a little showbiz: In January the audience at nearby Ketchum's nexStage Theater was surprised to see Moore stroll onstage for an unbilled performance in the play "Dinner with Friends." "She looked really healthy," says a theater volunteer. "She was great."
