The 17-year-old singer-and-actress - who has portrayed Jenny Humphrey in just three episodes of the current season so far - will not appear on screen after the episode which airs next Monday (29.11.10), reports website Deadline.
Though representatives for the TV series have refused to comment on the claims, insiders insist Taylor's airtime has been shelved for "strictly creative reasons".
Friends of the star - who fronts rock band The Pretty Reckless - insist she doesn't care about the show anymore and is only concerned about her 'Gossip Girl'pay cheque.
One pal told UsMagazine.com: "She only does the show for the money. 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."
Taylor - who has starred in 'Gossip Girl'since the pilot episode -previously confessed she doesn't feel close to any of her co-stars, who include Blake Lively, Chace Crawford and Leighton Meester, on the show.
She said: "I'm not really close with my cast. We're all cordial and nice to each other, but we're not really friends outside of the set."
