Will they or won't they again? Heidi Montag and Spencer Pratt, the reality-TV couple whose on-again, off-again relationship has been chronicled by MTV's "The Hills," weren't present at a panel celebrating the series Tuesday night because they're preparing for their Saturday wedding, the show's executive producers told the crowd at the William S. Paley Television Festival.

"It's a big gigantic event that takes the two of them to pull off," said Adam DiVello. "And a white dress," added Liz Gateley. DiVello said the show's crew was preparing to film the event. It won't be the first time that Montag, 22, and Pratt, 25, have attempted to tie the knot on camera. The pair appeared before a deputy commissioner at a Beverly Hills courthouse last December — but didn't say "I do" — after acknowledging their Nov. 19 marriage ceremony in Mexico was only symbolic.

Of those "Hills" cast members present at the PaleyFest panel — Lauren Conrad, Whitney Port, Audrina Patridge, Brody Jenner, Lauren "Lo" Bosworth and Stephanie Pratt — only Jenner, Bosworth and Pratt raised their hands when asked if they were invited to the ceremony. Pratt defended her brother's devotion to Montag.

"At the end of the day, Heidi is the most important person in his life," said Pratt.

Other tidbits uncovered during the panel: Crew members said they often make deals with the paparazzi so they can film the show in peace, and producers said they're in negotiations for another season.
