WATCH: Taylor Momsen Meets Tim Gunn on 'Gossip Girl'

Tim Gunn may not like Taylor Momsen very much, but the feuding duo managed to pull it together while filming. After working with the actress/singer on the set of Gossip Girl for his guest spot, Tim got a taste of what Taylor is really like. Catch their clip together after the jump!

“What a diva!” Tim told E! News last month of what it was like working with Taylor. “She was pathetic, she couldn’t remember her lines, and she didn’t even have that many. I thought to myself, ‘Why are we all being held hostage by this brat?’ ”

“I’d say, ‘You know young lady, there are hundreds of thousands of girls who are just as attractive and even smarter than you. Why are you acting like this show is a huge burden on you?’ ” Tim said. “She was on her phone during every break, I wanted to tell her, ‘If you weren’t on your BlackBerry, you can retain this stuff.’ ”

Taylor and her camp's response — "We don't respond to name calling."

Check out the clip from next week's all new episode of Gossip Girl — marking the return of Jenny Humphrey.
