momsen230.jpgTaylor Momsen will have to be content with troublemaking off screen, apparently.

The actress and her co-star Jessica Szohr will no longer star on the CW's Gossip Girl, TVLine reports.

Momsen played Jenny and Szohr played Vanessa. Momsen had made it quite clear in past interviews that she wants to focus on her music (the 17-year-old fronts The Pretty Reckless) and her on-set antics have made headlines. Tim Gunn guest starred on the show in November and called Momsen a "diva" and "a brat."

Gossip Girl is coming up on its fifth season. The show's core cast -- Blake Lively (Serena), Leighton Meester (Blair), Penn Badgley (Dan), Ed Westwick (Chuck) and Chace Crawford (Nate) -- will all be back in the fall.

In addition - one star will be promoted to series regular status and become a main character on the show. See who after the jump!
