Justin Bieber who makes his acting debut on the season’s first episode of CSI — kept silently mouthing other actors’ lines!
“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-syncing when the other actors speak,” a source American tabloid the National Enquirer.
“It’s hilarious — but damned expensive!”
Justin will guest star on the show’s Sept. 23 season premiere. He’ll also return for the fifteenth episode of the season, which will air in Feb. 2011.
