Demi Moore seems to have vanished from the face of the earth -- or at least the face of Hollywood, notes PEOPLE. Moore, once the highest paid actress in Hollywood, last year starred in "Passion of Mind," which came and went with hardly a ripple. Although she's producing a number of projects, says the magazine, she has no starring role upcoming for the foreseeable future and she's closing in on the dreaded four-oh. But PEOPLE hears that she's happy these days just playing mom in Idaho to her three girls, Rumor, 12, Scout, 9 and Tallulah, 7, taking them to school and the movies. Her divorce from Bruce Willis finalized last fall, she's still dating her martial arts-instructor boyfriend, Oliver Whitcomb. Less is Moore, it seems.
