Taylor Momsen Suspended from "Gossip Girl"

Are Taylor Momsen's Gossip Girl days over?

The increasingly controversial 17-year-old actress will begin an "indefinite hiatus" from Gossip Girl following next Monday's episode, sources tell Deadline. Reps for the CW and Warner Brothers declined to comment.

Momsen has played Jenny Humphrey, kid sister to Dan Humphrey (Penn Badgley) since the CW soap debuted in 2007. Although a series regular, she has only appeared in three episodes so far in the current fourth season.

"She only does [the show] for the money," a source explains to Us Magazine. "She works hard on Gossip Girl but doesn't care about the plot or the other cast members. She treats it like a 9-5. No emotional investment."

Momsen, who also fronts the rock band Pretty Reckless, has grown up since her big-screen debut at age 7 as cute Cindy Lou Who in How the Grinch Stole Christmas -- raising eyebrows with her skimpy, intensely Gothic wardrobe, notoriously foul-mouthed interviews and angry, age-inappropriate antics.

The new Us Weekly even reports that, for her Oct. 21 Pretty Reckless concert at NYC's Don Hill's (in which she flashed her breasts to the crowd) Momsen had a startling request: "Her rider included a full bar in her dressing room," an insider told Us. "That was rejected -- she's underage!"

Taylor Momsen Flashes Crowd At NY Concert

Taylor Momsen is turning into quite a shock rocker.

First, the Gossip Girl star posed on the November/December cover of Revolver in a barely-there outfit – and with some serious firepower, including a rifle, a handgun and a packed holster on her thigh.

Now the Pretty Reckless rocker is upping the shock factor: On Thursday in New York, Momsen, 17, flashed her breasts during a concert with her band.

Momsen was running her hands over her chest while singing and pulled down her ripped shirt – to briefly reveal to the crowd that she had black tape in the form of an "X" covering her most private parts.

Taylor Momsen Feels Objectified By Fame

Taylor Momsen feels like a "product".

The 17-year-old singer-and-actress - who appeared in her first commercial when she was just three years old - believes she has learned more about herself and her career as she has got older.

She said: "You get more insight as you get older, on everything.

"I kind of woke up one morning and was like, 'Oh I see what's happening, I get everything.'

"I woke up and was like, 'I get it, I'm a product.' "

The Pretty Reckless singer - who achieved widespread fame aged 14 after starring in US drama series 'Gossip Girl' - wasn't prepared for fame but insists she doesn't worry about living her life in the spotlight or what other people think of her.

She added: "Fame just kind of happens overnight. No one prepares you for it. On 'Gossip Girl', I was just going to work, doing what I've always done, and then all of a sudden you're like, 'Woah!'

"But you get used to it. You ignore it - because whatever people say about me doesn't bother me at all. If you're in high school or college or at work, someone's not going to like you. It's inevitable. But it doesn't mean anything."

Kelly Rutherford Defends Taylor Momsen

Kelly Rutherford's not worried about Taylor Momsen, crazy antics or not.

On Gossip Girl, Rutherford, 42, played stepmom to Momsen's Jenny Humphrey -- until the 17-year-old was asked to leave the show last month for an indefinite hiatus.

But Rutherford told Hollywood Life that Momsen has just shifted her focus from acting to music (Momsen fronts the band Pretty Reckless.)

"Her passion has just really become her music," Rutherford said. "Taylor's out there doing her music and if you hear her music you understand why she is so passionate."

Still, Momsen's departure from the show coincided with her increasingly dark reputation: the former kid star has flashed her breasts to a concert crowd, given countless potty-mouthed interviews and even requested a full bar on her tour rider despite being underage.

"I think she's young," Rutherford said. "And is exploring her world and she's exploring being an artist. I think it's important to be fully expressed."

"She works hard on Gossip Girl but doesn't care about the plot or the other cast members," a Momsen source recently told Us. "She treats it like a 9-5. No emotional investment."
