Sheena Easton. People forget that she got her start on a reality TV show, so she knows the pressure these kids are under. Plus, she's funny, and her catalog includes all kinds of music: Ballads (''For Your Eyes Only''); country (''We've Got Tonight''); dance-funk (''U Got the Look''); pop (''Strut'') and ...um, whatever ''Sugar Walls'' would be! —Paul
