Gossip Girl's Jenny Humphrey might be staying longer with her mother this season at the Upper East Side, as actress Taylor Momsen has been reportedly put in "indefinite hiatus" from the popular television series.

Last season saw Jenny Humphrey banished by Upper East Side's Queen Blair Waldorf, played by Leighton Meester, for sleeping with her boyfriend Chuck Bass. Taylor Momsen was said to have been put on leave for "creative reasons" as she pursues her music career with her band Pretty Reckless.

But now, it seems that there's another reason for her impending hiatus. Apparently, Taylor has been acting like a diva on the set of Gossip Girl. It was reported that Project Runway designer Tim Gunn blasted the actress for not memorizing her few lines for last Monday's episode.

"What a diva," the designer told E! News.

"She was pathetic, she couldn't remember her lines, and she didn't even have that many. I thought to myself, 'Why are we being held hostage by this brat?'"

Insiders from the show told the Daily Mail that Taylor Momsen will still be with the show, but her character Jenny Humphrey will be on-screen as little as possible. She will not be seen for at least four consecutive episodes, beginning with the December 6 midseason finale.
