Who is the 'Seinfeld' Reunion's Biggest Diva?

"Extra" caught up with Julia Louis-Dreyfus at the WB fall lineup party, and we couldn't help but ask about the highly-anticipated "Seinfeld" reunion on "Curb Your Enthusiasm"!

Julia tells "Extra," "We've done it. We shot it. It's in the can, baby! They are editing it as we speak."

It's been over a decade since the gang worked together, so who was the biggest diva on set? Julia tells all in this clip!
