Darren & Naya on "Moving" Cory Monteith Tribut

"It's the worst thing that's ever happened to me," Naya Rivera admitted during last night's MTV Video Music Awards. "It is the hardest thing to do. It's been the worst week ever."

"We're shooting it right now. It's tough to shoot," Darren Criss adds. "It's something that needs to happen for the fans. I don't know; it's going to be tough. But it will be very poignant and hopefully very moving, and just that: a tribute. Hopefully it will be a good tribute to Cory."
