DIRECTOR MUZZLES LIP-READER BIEBER

GOOD NEWS: Every female on the “CSI” set absolutely adores mop-haired popster JUSTIN BIEBER, 16, who’s making his acting debut on the season’s first episode.

BAD NEWS: Nobody, male or female, thinks the star singer will be displaying an Emmy next to his platinum albums anytime soon! It isn’t just that the troubled kid (who’s playing a troubled kid) lacks acting chops – the director had to keep yelling “CUT!” during his scenes and remind him to stop silently mouthing other actors’ lines.

Chuckled My Spy: “It’s good Justin’s got everyone’s lines memorized so he knows where he’s at in the scene, but the camera keeps catching him lip-synching when the other actors speak. It’s hilarious – but damned expensive!”
