Seems like Little Jenny Humphrey has made another enemy even more powerful than Blair Waldorf.

In a news bit by E! News, Tim Gunn has more than a few words to say about Taylor Momsen, the actress who brings good girl gone wrong Jenny Humphrey to life on Gossip Girl. After shooting a guest role on the show, Tim Gunn had to witness Momsen's less than perfect attitude on the set and had an unbearable urge to tell GG's resident "diva" to "make it work!" Literally.

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

Gunn claimed that Momsen stayed on her Blackberry nonstop in between takes, which he felt was the catalyst behind Momsen's lapse of memory when it came to her lines, annoying the entire crew and director in the process. Sweet Lord, Little J!

Gunn labeled his co-star "sad" and "pathetic", and if Tim Gunn has to use those words to describe you, then he seriously has a problem with your behavior.

Taylor Momsen's character of Jenny was banished by Blair Waldorf (Leighton Meester) out of the Upper East Side in Gossip Girl's season finale in May for sleeping with Chuck Bass (Ed Westwick), Blair's on-again/off-again boyfriend on the show. The "banishment" got fans and media speculating on if Momsen would return to the show in the fall at all, and if so, for how long. The mystery was solved when it was revealed that Jenny's absence was due to Momsen touring with her band, The Pretty Reckless, this fall. Although, Tim Gunn's account of Taylor Momsen's behavior could be evidence to another reason Momsen's not there any more. Is Taylor Momsen the Gossip Girl answer to Grey's Anatomy's Katherine Heigl debacle?

Tim Gunn's appearance on the show will coincide with Jenny's return to participate in this year's Fashion's Night Out, which will be the fourth episode of the season.

Do you guys believe Tim Gunn's story? Or was he being a bit harsh?
