SHE was the secretive, troubled teenage lass who put on a happy-go-lucky front in Tabing Ilog, the sexy party animal with a desperate need to belong in the youth flick Trip, and most recently a stubborn but ultimately good-hearted singing star in the teleserye Bituin. Twenty-one-year-old Desiree de Valle may play the problem child bit really well, but it is in the villainess roles that industry seers predict she will really make it big. And why not? With her strong woman features—the full lips, the big, bold eyes under brows forever raised, that amazing brown skin—she can very well be the next Cherie Gil, who just happened to be the mother in Bituin, and who, incidentally, was the original Problem Child.
