The event took place on the soon-to-be historic Wisteria Lane on the famed Universal Studios backlot -- a place that Teri Hatcher has called home for eight years, making the night especially emotional as this marks the program's last season.

"It's the last big celebration on Wisteria Lane," said Teri, who sang at the event, as did her 14-year-old daughter Emerson and co-star James Denton's group, That Band from TV. "It isn't over for us. I guess it's the right time for it to be over, because that's what the network and the producers decided. But it doesn't feel like it's over because there's no life in it. I guess maybe that's why they decided to let it go when they did -- because they wanted it to still have life in it. And it does."

Andrea Bowen revealed that Tuesday will be their last day of shooting and added, "It's going to be hard."
