Actress-turned-singer Taylor Momsen has banned music fans from recording her live in concert - after she was caught on tape baring her breasts at a New York show last week (21Oct10).
The 17 year old was captured on camera pulling down the neckline of her top and exposing two black pasties stuck over her nipples.
The footage made it online, forcing the Gossip Girl star to install strict new rules at gigs.
Momsen took to the stage again in Los Angeles on Wednesday (27Oct10) - and stunned the crowd by asking everyone with a camera or mobile phone to put it away.
She told the crowd: "I know this is the modern age and everyone's got cameras and cell phones and video cameras. But I'd really appreciate it if you'd put that f**king s**t down.
"I know it's very cool to videotape and put it on YouTube the next day. But, frankly, it completely takes away from the show. I'd thoroughly appreciate it if you'd put that s**t down and put your hands in the air…I want everyone's hands in the f**king air."
